Nowadays ‘round bolts’ come as standard on all new Mercs and, according to ze Germans, they’re designed to distribute torque more evenly and prevent slipping over the more usual hex-type jobs.

Of course there’s also the added bonus that they look just like locking wheel bolts and that can help act as a deterrent to thieving scum.

Well, TPI can now supply these for most other cars that run bolts as standard and they’ll do you a set of 20, complete with four proper lockers, all for the measly sum of 30-quid. You can’t say fairer than that can you?
