Self-Clinching (Nuts & Studs)
Self-clinching fasteners are specialized fastening products used in sheet metal assemblies. These fasteners are designed to provide a permanent fastening solution in thin metal sheets where it may not be possible to use bolts, screws, or other fasteners. Self-clinching fasteners feature a shank with grooves or serrations, an undercut region, and a clinching ring or flange. These features allow the fastener to be permanently installed into a pre-punched or pre-drilled hole in a sheet metal panel.
