Webb16 maj 2024 · UNF Threads. UNF threads are unified fine pitch threads. Allow for closer adjustment accuracy due to the smaller helix angle. Require less torque to develop equivalent bolt preloads. Fine thread is stronger in both tension (due to larger stress area) and shear (larger minor diameter) Less tendency to loosen since the thread incline is … WebbTap Drill Sizes for 5/16 - 32 UNEF If not specified, assume a thread depth of 75%.
