Single Thread U-Nuts are used where a full bearing surface on the lower leg is desired. During assembly, these high-performance "U" nuts are placed over the edge of a stamped panel, or through a pre-stamped slot, and are simply pushed until the rear of the fastener locates against the plastic or metal panel edge or snaps into the clearance hole. They are self-retained in the screw-receiving position to provide simple, rapid attachment of mating panels and cannot turn as the screw is driven.

These U-Nuts will not freeze on screw threads. In fact, the U-Nut's impression actually cleans out rust, dirt or paint clots from the screw threads as they are removed.
