Thread Height

Thread Height

Thread height is the distance between the crest and the root of the thread, normal to the axis of the thread. Several issues are easily detected by simply inspecting thread height.

Proper thread height maximizes the performance of any threaded connection. Thread height inspection is required by API. Thread height affects the interchangeability and the integrity of the threaded assembly.
