Extruded "U" Nuts
Clip Nut U-type fasteners are used to clamp together body parts at their seams & allow for a certain degree of alignment before installation. The multi-thread feature gives it more strength and retention than a regular single thread “U” or “J” nut. They have either a USS coarse thread or metric regular pitch thread. Extruded U Nuts are used with body bolts on door panels; bumper covers, hood hinges, fenders, radiators and general purpose fastening, likely at points that require more support than a standard plastic body clip.
