This nut secures the brake drum to the rear axle with a torque of 36kg/m or 136Nm.There are many of these nuts on the market, but a large proportion of them are not made of the correct material and workmanship. So there is a big chance that they can break and your brake drum (and thus wheel) can come loose. Our nuts are made like VW used to make them and are first stamped (forged) and then hardened and are therefore very strong.Don't take any risks and use the right nuts.
