WebInternal thread shear is calculated in a similar manner as external thread shear. According to FED-STD-H28/2B, the thread shear area for an internal thread is calculated by: where d p.int is the pitch diameter of the internal thread and L E is the length of thread engagement, which is calculated in the same manner as for the external thread shear. WebLength of Engagement: The tolerances specified in the ASME B1.5-1997 standard are applicable to lengths of engagement not exceeding twice the basic major diameter. Major Diameter: The maximum diameter of a thread which is diameter of the crest of a male thread or root of a female thread.
