UNC and UNF - Unified Coarce and Unified Fine Inch Threads
UNF – Unified National Fine Thread. Female and Male UNC/UNF threads are both parallel. The UNC/UNF flank angle is 60°. Unified threads comes in three different classes: for applications where a liberal tolerance is required to permit easy assembly even with slightly nicked threads.
Unified Thread Standard - Wikipedia
The Unified Thread Standard (UTS) defines a standard thread form and series—along with allowances, tolerances, and designations—for screw threads commonly used in the United States and Canada. It is the main standard for bolts, nuts, and a wide variety of other threaded fasteners used in these countries.
