There are usually several types of thread in the head area of a bone screw, which places special features on the drive. Bone screws can be self-tapping. The most important parameters are the mould of the drive, taper, pitch and the geometry of the spanner flats. Due to the tolerances of approx. 10 µm to 20 µm, the requirements for measurement uncertainty are high. The measuring time requirements are very high, as a 100% check is usually carried out. Due to the thread pitch, a 5-axis system is recommended as a measuring machine.
