- the adapter can be placed on all common screw heads if the dimensions of the adapter are selected accordingly. Since all known wheel bolts for vehicle wheels are in one dimensional range with slight deviations upwards or downwards, there is the possibility that only three sizes can be used to grasp all known wheel bolts or wheel bolts or wheel nuts.
- the cap-shaped component of the adapter has an interior and a cross-sectional shape that enables it to be placed on conventional screw heads, the cross-section of the cap-shaped component also being hexagonal, which then also gives the possibility of placing the adapter on screw heads that have a circular shape Have cross-section.
- Essential is, however, that the outer wall surface of the outer part of the adapter has a cylindrical shape in order to avoid attachment of actuating tools.
- An adapter with a component, the cap-shaped section of which has a circular cross section can also be placed on the head of a hexagon screw, since in all cases when the inner part is tightened against the outer part of the adapter, the form grippers are pressed against the screw head, which grip around it like a collet .
