ABSTRACT:
A pin thread profile mold includes two parallel spaced apart plate type thread profile gages. A cast is made with the mold positioned adjacent the thread with the plates parallel to the thread axis and the plane midway therebetween radial to the thread axis, the mold-thread interface being caulked with clay. After being placed adjacent the thread the mold is packed with self hardening plastics material in the plastic state, such as dental plaster. After the plastics material has hardened the cast is removed from the thread and sent to a laboratory for comparison with a desired profile.
