WebUNC Thread ANSI/ASME B1.1. UNC - Unified Coarse Thread. The old definition NC is comparable with the metric thread. The new term UNC is comparable with the ISO metric thread. NC and UNC threads are interchangeable, in an analogous manner like the metric and the ISO metric thread. The flank angle is 60°. WebBefore you design your next product or make updates to an existing product, consider partnering with Optimas to take advantage of our many capabilities. The table below shows the types of screw threads, sizes, and specifications of Unified Coarse (UNC), Unified Fine (UNF) and Unified Extra Fine (UNEF) threads.
