Pitch diameter for 1/4-20
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 … WebbMeasuring Bolt Dimensions & Diameters. The size of a bolt is determined by the diameter of the bolt’s shank (separate from the bolt head). Bolt diameter is typically separated into three categories: Major diameter: The largest and most outer diameter of a bolt’s shank. Pitch diameter: The diameter where the thread thickness = the space ...
