EFC International - Carbon Steel and Stainless Steel Self-Clinching Nuts

These Steel and Stainless Steel Self-Clinching Nuts provide strong load-bearing threads in sheet metal and other thin section assemblies. These nuts meet specification features of MIL-N-45938/1. All self-clinching fasteners install into a round hole, which may be punched or drilled in ductile materials. They provide a permanently attached fastener, which becomes an integral part of the panel or frame and eliminates the problems associated with loose hardware. Self-Clinching fasteners provide added value by speeding initial assembly as well as servicing in the field, keeping costs to a minimum.

Fastener Features	N/A Self-Clinching
Features and Benefits	N/A Self-clinching fasteners are pressed into holes in sheet metal by applying a steady squeezing force. This results in the cold-flow of sheet material, which is displaced by the knurl, into the undercut area on the shank of the fastener. Once fully embedded, the knurled area prevents torque-out during tightening of mating part.
