Why this one
Ratcheting double ring
A reversible ratchet in each end means you don't lift off and reposition between strokes. Flip the wrench end-for-end to reverse direction.
18 teeth
The ratchet has 18 teeth for extra strength, and it is fibre reinforced for outdoor sites.
25° offset heads
Both ring heads are offset at 25°, giving your knuckles room and letting you seat the wrench on bolts in recesses or behind hardware.
Sizes from 6 x 8 mm
Sold individually, with a different size at each end, from 6 × 8 mm up to 21 × 22 mm. The 6 mm has a 6 point ring end and the others have 12 point.
Read the full description
Large metric fasteners — 17 mm through 22 mm — hold together the parts that take the most stress: axle nuts, control arms, exhaust flanges, and structural cross-members. When you know exactly which two sizes the job requires, a single double-ended tool beats digging through a full set.
Both ring heads are offset from the handle, giving your knuckles room to swing and letting you seat the wrench on bolt heads that sit in recesses or behind adjacent hardware. At this size range, where you are pushing harder, knuckle clearance is not a convenience — it is protection.
The ratcheting mechanism eliminates the need to lift off and reposition between strokes. Flip end-for-end to reverse, keeping the operation glove-friendly and switch-free. Fewer parts mean less to go wrong under the higher loads these fastener sizes demand.
Overall length is 235 mm (9.3 in) and weight is 281 g — enough mass for confident torque delivery, compact enough to fit inside wheel arches and between frame rails. Sold individually so you can buy the exact pair of sizes your work requires, whether it is one wrench to complete a collection or a dedicated tool for a recurring service procedure.
