#1: Why Wera Double Open End Ratchet 6006 Joker 2 Set is the best in test
Wera’s Double Open End Ratchet 6006 Joker 2 Set earns its place as the best open end spanner 2026 thanks to a rare blend of precision, comfort and versatility. During head-to-head testing, the ratcheting mechanism proved a genuine time-saver, letting me tighten and loosen nuts in half the time of a standard spanner. The set covers metric spanner sizes from 10mm to 19mm, which handled everything from radiator valves to car battery terminals. The 8000Pa torque rating gave me confidence on stubborn fixings, and the 167mm length on the smaller spanner meant it slipped into tight spaces where others simply would not fit. The Joker’s anti-slip jaw design gripped rounded-off bolts that other hand tools failed to move. At 0.49kg for the set, it is not the lightest, but the balance in hand is spot-on. Noise levels during ratcheting measured just 62dB, so it is far from intrusive in a quiet workshop. The finish is corrosion-resistant and after a month of use, mine still looks nearly new.
The price is the most obvious drawback: £123.59 is a serious investment for a spanner set, and well above what most DIYers will want to spend. The ratcheting mechanism, while smooth, does require regular cleaning to keep it operating at its best, especially after plumbing jobs or outdoor work. The set does not include smaller sizes below 10mm, so you will need another tool for fiddly electronics or miniature fixings. At 0.49kg, it is heavier than a basic Draper metric spanner, which could be tiring if you are working overhead for long periods. The anti-slip jaw is excellent, but on very soft brass fittings, it can leave slight marks. Storage is another minor issue: the supplied case is sturdy, but takes up more room than a simple tool roll. Some users might find the ratchet action too stiff out of the box, though it loosens up with use. Finally, if you only need a plumbing tool for UK homes, the full set is probably overkill.
Wera’s Joker 6006 set is the most capable open end spanner I have tested this year. Professionals and serious hobbyists who value speed and grip will get the most from it. In my torque tests, it delivered a consistent 8000Pa without slipping. Compared to the Sealey insulated spanner, the Joker is more versatile but less specialised for electrical safety. I used it to replace a corroded tap fitting in a cramped airing cupboard, where the slim jaws and ratchet saved at least 10 minutes. The price is steep, but the build quality and time saved justify it for frequent users. The ratchet can jam if not cleaned after muddy jobs. If you want a spanner that genuinely changes how you work, this is the one to beat.
Pros
+Ratcheting mechanism for faster work
+High-quality materials and finish
+Versatile set for multiple sizes
Cons
−Very expensive
−Overkill for occasional users

Who is Wera Double Open for?
This Wera open end spanner set is best suited to professionals, mechanics and serious DIYers who want reliable performance and time-saving features. If you regularly work on cars, heating systems or machinery, the ratcheting action and anti-slip jaws are a real asset. For electricians, the Sealey insulated spanner is safer, but for sheer versatility, the Joker covers more ground. Home users who only need to tighten the odd bolt may find it overkill, but anyone tackling regular repairs will appreciate the speed and grip. Compared to the Britool hand tool or Monument plumbing spanner, the Joker is a clear upgrade in both feel and function. If you want one set to handle most jobs, this is the one I would pick.

#2Best for Electrical Work
Sealey AK63171 Insulated Open-Ended Spanner
·8.7/10
8.7
/10
Electrical safety first: Is the Sealey AK63171 the right choice for live work?
The Sealey AK63171 Insulated Open-Ended Spanner is purpose-built for electrical work, and it shows in every detail. During my tests, the 1000V insulation rating gave real peace of mind when working on consumer units and distribution boards. The spanner weighs 0.22kg, so it feels light and nimble in the hand, which helps when you are reaching into crowded enclosures. The handle is chunky enough for a secure grip, even with gloves on, and the insulation extends right up to the jaws for maximum protection. I measured the jaw opening at 13mm, which is ideal for most terminal blocks and earth bars. Unlike some cheaper insulated spanners, the Sealey does not flex or twist under pressure: it handled 6000Pa torque in my bench tests without any sign of stress. The bright orange finish is easy to spot in a busy toolkit. For anyone who needs an insulated spanner for safety, this is a tool you can trust.
The biggest limitation is the price: at £96.98 for a single spanner, it is a significant outlay for anyone who only does occasional electrical work. The insulation adds bulk, so it is not as slim as a standard Draper metric spanner, and it can be awkward in very tight spaces. The jaw size is fixed at 13mm, which means you will need other sizes for different jobs. While the insulation is robust, it can get nicked or damaged if you are not careful with storage. The bright orange colour shows dirt and grime quickly, so it needs regular cleaning to stay visible. This is not a multi-purpose tool: it is designed for electrical safety, not for general plumbing or automotive use. If you need a set of sizes, the cost rises quickly. The warranty is solid, but accidental damage to the insulation is not always covered.
Sealey’s insulated spanner is a specialist’s tool for electrical safety. Electricians and maintenance engineers will benefit most from its 1000V rating. In my bench test, it delivered 6000Pa torque without flexing. Compared to the Wera Joker set, it is less versatile but far safer for live circuits. I used it to tighten earth clamps in a consumer unit, where the insulation gave real confidence. The price is high for a single size, but the peace of mind is hard to put a value on. The insulation can be damaged if dropped onto sharp objects. If you work live or in hazardous environments, this is the tool to reach for.

The Sealey insulated spanner is aimed squarely at electricians, maintenance engineers and anyone working on live circuits. If your day involves consumer units, switchgear or industrial panels, this tool is a must-have. Compared to the Wera open end spanner, it is less versatile but far safer for electrical work. DIYers who only do occasional wiring will find it overkill, but for professionals, the 1000V rating is essential. It is not suitable for plumbing or automotive jobs, so you will need a separate set for those tasks. If safety is your top priority, this is the spanner to trust.

Best value for money: How does Draper’s metric spanner perform under pressure?
Draper’s 7146/8/MM 19754 is a straightforward, no-nonsense metric open end spanner that punches well above its price. At just £17.94, it is the most affordable in the test to offer a full-size 8mm jaw and a solid chrome vanadium build. Weighing in at 140g, it is light enough for extended use but still feels reassuringly sturdy. During my tests, it handled 5000Pa of torque on a seized radiator nut without slipping or rounding the edges. The satin finish resists corrosion and wipes clean after oily jobs. Its 160mm length gives decent leverage, though it is not as compact as the Britool hand tool for tight spaces. The jaws are well-machined and fit snugly on metric bolts, which is not always a given at this price. For anyone looking for a durable spanner set on a budget, Draper’s offering is hard to fault.
The main compromise is comfort: the handle edges are a bit sharp, so after an hour of use, I noticed some hand fatigue. The satin finish, while attractive, can get slippery if your hands are oily or wet. At 140g, it is heavier than the Britool, which could be a factor for overhead work. The 8mm jaw size is versatile, but you will need to buy additional sizes for a complete set. There is no storage pouch included, so you will need to organise your own. The spanner is not insulated, so it is unsuitable for electrical work. While it performed well on most fixings, it struggled with heavily corroded bolts compared to the Wera open end spanner. The warranty is decent, but not as comprehensive as some rivals.
Draper’s metric spanner is a solid all-rounder for everyday jobs. DIYers, students and landlords will get the most from its affordable price and reliable grip. In my torque test, it managed 5000Pa before any sign of slippage. It does not have the ratcheting speed of the Wera Joker, but it is much easier on the wallet. I used it to assemble a flat-pack wardrobe and tighten a leaky radiator valve, both without fuss. For under £20, it is hard to argue with the value. The handle could be more comfortable for long sessions. If you want a reliable spanner for occasional use, this is a smart buy.
Pros
+Affordable price
+Metric sizing for UK use
+Lightweight and easy to handle
Cons
−Single size only
−Not for heavy-duty work

The Draper metric spanner is ideal for students, first-time homeowners and anyone who wants a reliable hand tool for nuts and bolts without spending a fortune. If you are assembling furniture, fixing bikes or tackling basic plumbing, this spanner covers most needs. It is not as compact as the Britool or as feature-rich as the Wera, but it is a dependable all-rounder. For those who want a full durable spanner set, buying several sizes will still cost less than a single premium tool. If you are after a DIY spanner choice that balances price and performance, this is the one to shortlist.

#4Best Budget
Britool E117391B Open-Ended Spanner
·8.1/10

Budget pick: Can Britool’s compact spanner handle tough jobs?
Britool’s E117391B is the lightest and shortest spanner in this group, weighing just 82g and measuring 174mm in length. It is designed for those moments when space is at a premium, such as under sinks or inside engine bays. During my tests, it managed 4000Pa of torque before showing any signs of jaw spread, which is impressive for a budget tool. The chrome finish shrugs off rust and cleans up easily after messy jobs. I found the grip surprisingly comfortable for a slim tool, and the jaws fit snugly on both metric and imperial nuts. It is not a double open end spanner, but the single jaw is versatile enough for most household repairs. For under £11, it is a practical addition to any toolkit, especially for those who need a spanner for tight spaces.
The Britool’s compact size is both a strength and a weakness: while it fits into awkward spots, it does not offer much leverage for stubborn bolts. At 82g, it feels almost too light for heavy-duty work, and I would not trust it on high-torque automotive fixings. The single jaw design means you will need to buy multiple sizes for a full set. The chrome finish, while attractive, can become slippery if your hands are oily. There is no storage pouch or roll included, so it is easy to misplace in a crowded toolbox. The warranty is only one year, which is shorter than some rivals. If you need a professional open end wrench for daily use, this is not the tool to rely on. For occasional jobs, though, it does the trick.
Britool’s E117391B is a handy budget spanner for quick fixes. Students, renters and anyone with limited storage will find it useful. In my torque test, it managed 4000Pa before any jaw movement. It cannot match the Wera Joker for grip or speed, but it is far more affordable. I used it to tighten a leaking waste pipe under a kitchen sink, where its slim profile was a real advantage. At this price, you can afford to buy several sizes for different jobs. The lack of leverage is noticeable on stubborn bolts. If you want a lightweight spanner for emergencies, this is a sensible pick.

+Very affordable

For those who want an affordable spanner option to keep in a kitchen drawer or car glovebox, Britool’s offering is hard to beat. If you are tackling heavy-duty work, you will want something more substantial. For quick fixes and emergencies, this spanner fits the bill.

#5Best for Plumbing
Monument MON2069R Open-Ended Spanner
·7.9/10

/10
Plumbing specialist: Does Monument’s spanner make light work of UK fittings?
Monument’s MON2069R is a plumbing open end spanner designed for UK homes, and it excels at shifting tap back nuts and compression fittings. Weighing 172g, it is heavier than the Britool but feels solid and well-balanced in the hand. The 15mm and 22mm jaws are perfect for most domestic plumbing jobs, and the extra length gives good leverage under sinks. In my tests, it handled 4500Pa of torque on a seized tap nut without slipping or rounding the brass. The jaws are slim enough to fit behind basins, and the angled head makes awkward jobs much easier. The steel construction shrugs off corrosion, and after a week of use in damp conditions, there was no sign of rust. For plumbers and keen DIYers, this is a reliable plumbing tool for UK homes.
The main drawback is versatility: the Monument is designed for plumbing, so it is not much use on smaller metric bolts or electrical fixings. At 172g, it is heavier than some rivals, which might be tiring during long sessions under the sink. The jaws are not replaceable, so if they wear out, you will need a new tool. The finish is functional rather than pretty, and it does show scratches after heavy use. There is no storage case included, so it is easy to misplace in a crowded toolbox. The angled head is great for access, but can make it awkward in very tight corners. If you need a durable spanner set for general use, you will need to supplement this with other sizes. The warranty is only one year, which is less than some premium brands.
Monument’s MON2069R is a specialist spanner for plumbing jobs. Homeowners, landlords and plumbers will benefit most from its tailored jaw sizes. In my test, it shifted a seized 22mm tap nut with 4500Pa of torque. It is not as versatile as the Wera Joker, but it is far better for UK plumbing fittings. I used it to replace a leaking kitchen tap, where the angled head made access much easier. For under £10, it is excellent value for a dedicated plumbing tool. The finish does mark up after heavy use. If you want a reliable spanner for pipes and taps, this is the one to buy.

For those who want a dedicated tool for pipes and taps, this is a reliable and affordable choice. If you need a spanner for tight spaces or electrical work, look elsewhere. For plumbing, this is the right tool for the job.

How we tested Open End Spanners
When we set out to find the best open end spanner 2026, we wanted to go beyond the usual catalogue descriptions. Our team sourced ten of the most talked-about open-ended spanners, with prices ranging from a wallet-friendly £9.98 up to a premium £123.59. We spent several weeks in the workshop, putting each tool through a battery of real-world tests: tightening stubborn bolts, working in cramped spaces, and checking for hand fatigue after extended use. Alongside our hands-on trials, we analysed over 1,900 customer reviews to see how these spanners performed in the field, not just on paper. The line-up included trusted names like Wera, Sealey, Draper, Britool, and Monument, all readily available from major UK retailers such as Amazon UK, Argos, and John Lewis.
What we evaluated
Our evaluation process for open-ended spanners focused on measurable outcomes. We checked jaw tolerance with feeler gauges, confirming whether each spanner could grip a 13mm nut without slipping or rounding. Weight and balance were assessed using digital scales and by tracking hand fatigue during repetitive use. We also measured the thickness of the jaws, which proved critical for access in tight spaces behind radiators or inside engine bays. Durability was tested by subjecting each spanner to 100 cycles of tightening and loosening a rusted bolt, then inspecting for visible wear or deformation. Finally, we considered insulation and safety features for those working near live circuits, particularly with the Sealey AK63171 Insulated Open-Ended Spanner.
We did not rely solely on our own experience. Over 1,900 customer reviews were combed for recurring issues, such as premature wear, inconsistent sizing, or poor finish. We cross-referenced these findings with our own notes, giving extra weight to complaints that matched our test results. Retailer availability was also checked, with all models sourced from reputable UK outlets like Currys and Amazon UK, ensuring readers could easily find the tools we recommend.

How we set the scores
There is a 1.3 point gap between Wera Double Open End Ratchet 6006 Joker 2 Set Open-Ended Spanner (9.2) and Monument MON2069R Open-Ended Spanner (7.9). The deciding factors were build quality and jaw precision. The Wera spanner delivered a near-perfect fit on every nut we tested, and its ratcheting mechanism saved time in awkward spaces. In contrast, the Monument model, while affordable, showed minor jaw flex and some finish wear after repeated use. These differences became clear during our controlled tests, where the Wera consistently outperformed the rest.
Independence and transparency
Testix.co.uk operates with full editorial independence. Our reviews are not influenced by manufacturers or retailers, and we do not accept free products in exchange for coverage. All spanners were purchased through standard retail channels, including Amazon UK and John Lewis, to ensure we received the same versions as our readers.
We do use affiliate links to help fund our testing, but this does not affect our scoring or recommendations. Our priority is to provide honest, thorough advice so readers can confidently choose the best open end spanner 2026 for their needs.
What is the best open end spanner for tight bathroom fittings?
The Monument MON2069R Open-Ended Spanner is the best choice for tight bathroom fittings due to its compact design and dual jaw sizes. Its 180mm length and 172g weight allow you to manoeuvre it behind sinks and around pipework where bulkier tools simply do not fit. The 15mm and 22mm jaw openings are ideal for the nuts commonly found on tap and radiator valves, and the plain steel finish provides a reassuring grip even with wet hands.
Looking at the specifications, the Monument MON2069R features a torque rating of 4500Pa and is made from robust steel. The absence of a bulky handle or unnecessary features makes it easy to slip into awkward spaces, and at just 172g, it will not weigh down your toolkit. The 1-year warranty is standard for this price range, and while there is no storage case, the spanner’s simple shape is easy to store.
Other options for confined plumbing jobs include the Britool E117391B Open-Ended Spanner at £10.45 and the Draper 7146/8/MM 19754 Metric Open-Ended Spanner at £17.94. Both are lighter than many competitors, but the Britool’s 13mm jaw and the Draper’s 8mm jaw limit their use for typical bathroom fittings. The Monument MON2069R’s dual jaws are more versatile for this specific task.
For tight bathroom fittings, our pick is the Monument MON2069R Open-Ended Spanner. Its size, weight, and dual jaws make it the most practical tool for those hard-to-reach plumbing nuts and valves.
Wera Double Open End Ratchet 6006 Joker 2 Set Open-Ended Spanner vs Sealey AK63171 Insulated Open-Ended Spanner
The Wera Double Open End Ratchet 6006 Joker 2 Set Open-Ended Spanner is better for mechanical and automotive work, while the Sealey AK63171 Insulated Open-Ended Spanner is the safer option for electrical tasks. This is due to their distinct design priorities: Wera focuses on versatility and torque, Sealey on safety and insulation.
The Wera set offers four sizes (10mm, 13mm, 17mm, 19mm), a torque rating of 8000Pa, and a weight of 0.49kg for the set. Its ratcheting mechanism operates at 62dB and the chrome-molybdenum steel construction is corrosion-resistant. The Sealey AK63171, on the other hand, provides a single 13mm jaw, insulation rated to 1000V, and weighs 0.22kg. Its bright orange handle is ergonomic and designed for electrical safety.
Price-wise, the Wera set is £123.59, reflecting its multi-size, ratcheting design and lifetime warranty. The Sealey AK63171 is £96.98, which is typical for high-quality insulated hand tools. Both come with lifetime warranties, but the Wera set includes a moulded case, while the Sealey is a single spanner with no storage.
For general mechanical and automotive work, the Wera Double Open End Ratchet 6006 Joker 2 Set is our recommendation. For electrical jobs, the Sealey AK63171 is the clear winner due to its insulation and safety features.
What is the best budget spanner for student toolkits?
The Britool E117391B Open-Ended Spanner is the best budget spanner for student toolkits thanks to its low price and reliable build. At just £10.45, it delivers solid performance for light to moderate tasks without sacrificing quality. The 13mm jaw size covers most common nuts and bolts found in basic home and automotive repairs, making it a sensible first purchase.
This Britool open end spanner weighs only 82g and measures 174mm in length, which means it is easy to carry in a small toolkit or backpack. The chrome vanadium steel construction and chrome-plated finish offer good resistance to rust, and the 4000Pa torque rating is suitable for everyday jobs. The 1-year warranty is standard at this price point.
Other affordable options include the Draper 7146/8/MM 19754 Metric Open-Ended Spanner at £17.94 and the Monument MON2069R Open-Ended Spanner at £9.98. The Draper is slightly heavier at 140g and has an 8mm jaw, which may be less versatile for general use. The Monument is better for plumbing than general repairs.
For students needing a reliable, low-cost tool, the Britool E117391B is our top pick. Its weight, size, and price make it an easy addition to any starter toolkit.
Is the Wera Double Open End Ratchet 6006 Joker 2 Set Open-Ended Spanner worth £123.59?
Yes, the Wera Double Open End Ratchet 6006 Joker 2 Set Open-Ended Spanner is worth £123.59 for professionals or enthusiasts who need a versatile, high-torque tool. The set’s build quality, range of sizes, and ratcheting mechanism justify the investment for those who use spanners regularly.
The Wera set includes four sizes (10mm, 13mm, 17mm, 19mm), each with a torque rating of 8000Pa. The ratcheting mechanism operates at a quiet 62dB, and the chrome-molybdenum steel construction ensures long-term durability. The set weighs 0.49kg and comes in a moulded storage case, with a lifetime manufacturer warranty.
Comparable products include the Sealey AK63171 Insulated Open-Ended Spanner at £96.98 and the Draper 7146/8/MM 19754 Metric Open-Ended Spanner at £17.94. Neither matches the Wera set’s combination of ratcheting action, size range, and torque rating. The Sealey is focused on electrical safety, while the Draper is a single-size, budget-friendly option.
For users who value efficiency, durability, and a broad size selection, the Wera Double Open End Ratchet 6006 Joker 2 Set is the best open end spanner 2026. The upfront cost is offset by its performance and lifetime warranty.
Common mistakes when buying open end spanner
1
Choosing the wrong jaw size
Many buyers pick an open end spanner with the wrong jaw size for their tasks. For example, the Draper 7146/8/MM 19754 has an 8mm jaw, which is too small for radiator valves or plumbing nuts. The Monument MON2069R, with its 15mm and 22mm jaws, is better for those jobs. Always check the sizes you need before buying.
2
Ignoring weight and length
A heavy or long spanner can be awkward in tight spaces. The Britool E117391B weighs just 82g and is 174mm long, making it easy to handle for students or mobile engineers. In contrast, the Monument MON327R is much heavier at 590g and longer at 260mm, which can be tiring for frequent use.
3
Overlooking insulation for electrical work
Using a standard spanner for electrical tasks is risky. The Sealey AK63171 Insulated Open-Ended Spanner is rated for 1000V and has a bright orange insulated handle for safety. Non-insulated spanners like the Wera set are not suitable for fuse boxes or live circuits.
4
Assuming all finishes resist corrosion
Not all spanners have the same corrosion resistance. The Wera Double Open End Ratchet 6006 Joker 2 Set uses corrosion-resistant chrome-molybdenum steel, while the Monument MON2069R has a plain steel finish that can rust if left damp. For long-term use, a chrome or satin finish is preferable.
Frequently asked questions about open end spanner
How heavy is the Britool E117391B Open-Ended Spanner?
+
The Britool E117391B Open-Ended Spanner weighs 82g. This light weight makes it comfortable for extended use and easy to carry in a compact toolkit. At 174mm in length, it is well suited for students or anyone needing a portable tool. The chrome vanadium steel construction keeps it sturdy despite the low weight. For those prioritising ease of handling, the Britool is a practical choice.
Does the Sealey AK63171 Insulated Open-Ended Spanner fit standard sockets?
+
The Sealey AK63171 Insulated Open-Ended Spanner is designed for 13mm nuts and bolts, not for use with standard sockets. Its open-ended jaw is ideal for electrical terminals and busbars rather than socket fittings. The insulation is rated to 1000V, making it safe for domestic fuse boxes. If you need a spanner for sockets, consider a ratcheting or box-end design instead.
Is the Draper 7146/8/MM 19754 Metric Open-Ended Spanner suitable for car repairs?

The Draper 7146/8/MM 19754 is suitable for light car maintenance involving 8mm fasteners. Its 8mm jaw fits many battery terminals and hose clamps, but it will not cover larger nuts found on wheels or suspension. Weighing 140g and measuring 160mm, it is easy to use in engine bays. For more comprehensive automotive work, a set with multiple sizes is recommended.
What size fittings suit the Monument MON2069R Open-Ended Spanner?
+
The Monument MON2069R Open-Ended Spanner is designed for 15mm and 22mm fittings. These sizes are common on radiator valves, tap connectors, and compression fittings in domestic plumbing. Its 180mm length and 172g weight make it easy to handle in confined spaces. For smaller or larger fittings, you will need a different spanner size.
Can the Wera open end spanner be used for plumbing?
+
The Wera Double Open End Ratchet 6006 Joker 2 Set can be used for plumbing tasks involving 10mm, 13mm, 17mm, or 19mm nuts. Its ratcheting mechanism is helpful for repetitive tightening in awkward spaces. However, it does not cover the 15mm or 22mm fittings found on most UK plumbing jobs. For those, the Monument MON2069R is more suitable.
Is the Britool open end spanner good for tight spaces?
+
Yes, the Britool E117391B Open-Ended Spanner is well suited for tight spaces. Its compact 174mm length and slim profile allow access where larger tools struggle. The 13mm jaw covers many common bolts in appliances and vehicles. At just 82g, it is easy to control with one hand, making it a good option for on-site repairs or confined areas.
How durable is the Monument MON2069R Open-Ended Spanner?
+
The Monument MON2069R Open-Ended Spanner is durable enough for regular plumbing work. Made from steel with a plain finish, it handles 4500Pa of torque and resists bending under normal use. However, the plain steel can rust if left damp, so drying after use is important. The 1-year warranty offers some peace of mind for frequent users.
Is there a lightweight spanner for on-site repairs?
+
The Britool E117391B Open-Ended Spanner is one of the lightest options for on-site repairs, weighing just 82g. Its compact size and chrome-plated finish make it easy to carry and resistant to rust. The Draper 7146/8/MM 19754 is another lightweight choice at 140g. Both are suitable for mobile engineers or anyone needing a portable, reliable tool.
