For fastening the wheels, two types of fasteners are used, each of which has a different shape and length. First, we are talking about wheel nuts and wheel bolts. They can have a conical or spherical clamping part. The shape of such parts is selected according to the profile of the holes directly in the wheel rim. As a rule, it is presented in the form of spherical or conical recesses. When tightening the wheel mounts, a certain pair is centered - a sphere-sphere or a cone-cone. Shape matching is important because the joints ensure a snug fit as well as correct wheel alignment.

The usage of the wheel bolts

Spherical seats are usually on stamped metal discs. Tapered - forged or cast from light alloys. In addition, there are alloy wheels with spherical seats. When replacing them, as a rule, the wheel fasteners are also changed. Especially when it comes to nuts.

TOPRAN brand Wheel Bolt must be matched to the type of wheel rims. They are the ones that determine the length of the bolt. Forged steel wheels are much thinner than light-alloy cast ones. They use short wheel bolts. The latter ensure the mutual tightening of several elements, namely the wheel and brake discs, as well as the hub.
