Self-Clinching fasteners are threaded nuts, studs or standoffs that are mechanically pressed into metal, becoming a permanent part of the panel, enclosure or bracket. One of the biggest strengths of self-clinching fasteners is how securely mounted they are into the part or enclosure. 

Self-clinching nuts provide strong, load-bearing threads to accept bolts and screws in thin sheet metal applications. They’re typically pressed into the metal using a manual or hydraulic press and swage the surrounding metal, which makes them a strong and permanently affixed component.

Self-clinching standoffs have through-hole full-through thread self-clinching standoff and blind-hole self-clinching standoff. The difference between through-hole full-through standoff and blind hole standoff is whether the inner hole is open and the thread length is different. 

Self-clinching studs are mainly divided into two types: round head type and hexagon head type: the S part of the self-clinching stud is round head and flower teeth, and the clinch method is basically the same as the flower tooth self-clinching nut introduced above. The S part of the hex head is composed of hexagon head and concave and convex.
