UNC nuts refer to the UNC thread, Unified National Course, which is a standard thread form used for fasteners in the United States, and are used in applications within machinery for automotive, engineering, and manufacturing. They are used to secure objects together by matching with the corresponding UNC bolt or screw.
UNC threads have a relatively larger thread pitch compared to finer threads. The thread pitch refers to the distance between adjacent threads and is typically measured in threads per inch (TPI).
We stock them in various shapes and styles including hex nuts, nylocs (nylon insert nuts), castle nuts, slotted nuts, wing nuts, dome nuts and half nuts (jam, lock). They come in zinc, stainless, and unplated self colour.
