• U-Shaped Speed Nuts®

    U-Nuts, also called U-Shaped Speed Nuts®, are self-retained in the screw-receiving position to provide simple and rapid attachment of mating panels. They will not turn when the screw is driven and will not corrode or freeze on screw threads. Typically, U-nuts are used where a full bearing surface on the lower leg is desired. During assembly, these high-performance, single thread nuts are placed over the edge of a stamped panel, or through a pre-stamped slot, then pushed until the fastener inner back locates against the plastic or metal panel edge or snaps into the clearance hole. In addition, the U-Nut's impression actually cleans out rust, dirt or paint clots from the screw threads as they are removed.
