Miniature Self-Clinching Self-Retaining Nuts are designed to provide strong threads in a minimum of space. They are available with locking and non-locking threads and are directly interchangeable with industry standards. All self-clinching fasteners install into a round hole that 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.

Features and Benefits

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 the mating part.
