WebThere are three standard thread series in the Unified Screw Thread System that are highly important for fasteners: UNC (coarse), UNF (fine), and 8-UN (8 thread).A chart listing the standards sizes and thread pitches with their respective thread stress areas is listed in the Fastenal Technical Reference Guide, along with a special series designated UNS. WebMay 16, 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 …
