This paper describes the design and development of a high speed automatic testing system for threaded components, based on the contact measuring method. The measuring system consists of both mechanical and electronic elements. The measuring principle is based on a high speed clamping mechanism for the bolt and provides a linear and angular movements. These are used for testing the thread profile and/or the helix path. The system is capable of detecting the errors which may occur due to the manufacturing process itself. Different bolt sizes (M6, M8, and M16) were tested and the results of both the thread form and the helix path are presented. The maximum linear velocity used was 2 mm/sec, while the maximum angular velocity used was 6.25 rad/sec for the bolt M16. The accuracy achieved using this system is within ± 0.009 mm.
