Brüder Mannesmann M 160-EXTRA Car X-Spanner (350 mm)
This M 160-EXTRA X-spanner from Brüder Mannesmann is plain and practical — exactly the sort of tool you want in the boot for when a tyre lets you down at the worst possible moment. It gives you the leverage needed to shift wheel nuts quickly, without any faff or fiddly bits.
sturdy construction and finish
Built from hardened steel with a silver painted finish, this cross key is made to take regular use. The paint helps fend off surface rust and the hardened sockets resist rounding under pressure. It’s not flashy kit, but it’s tough and dependable — just what you want roadside or in the garage.
what sizes does it fit?
The four-way head covers the most common sizes in one compact tool: 17 mm, 19 mm, 21 mm (sometimes marked as 13/16″) and 22 mm. Those sizes will fit the majority of passenger cars, so it’s handy for swapping wheels at the kerb or doing routine jobs at home.
practical length and leverage
At 350 mm overall, the arms give you proper leverage to break stubborn wheel nuts without having to stand on the tool. That extra reach makes a noticeable difference when nuts are seized from corrosion or have been over-tightened previously. Remember, though, it’s not a torque wrench — use a proper torque tool to tighten to manufacturer settings.
easy to use, easy to keep
The X-shape is simple and compact, so it tucks away neatly in a boot compartment or toolbox. No set-up, no loose parts to lose. If the nuts are very rusty, give them a quick squirt of penetrating oil and wait a few minutes — that often saves a lot of swearing and elbow grease, especially in winter.
use cases and common questions
- Emergency tyre changes at the roadside — plenty of leverage and the right sizes for most cars.
- Home or hobby mechanics doing seasonal wheel swaps — simple, reliable and fuss-free.
- Not a substitute for a torque wrench when final tightening to manufacturer specs is required.
- If you see a wildly small weight listed (for example 9.07 g), that’s almost certainly a misprint — expect a solid, heavier steel tool.
Worried about fitment? Check your vehicle’s wheel nut sizes first, but those four sockets cover the common ones. For smoother jobs, keep the spanner clean and dry in storage, and treat stuck nuts with penetrating oil before levering them off. In short, the Brüder Mannesmann M 160-EXTRA X-spanner is a sensible, durable bit of kit — simple, reliable and a proper help when you need it most.
