NUTS - SELF RETAINING SELF-CLINCHING STEEL HEAVY DUTY

Product Description

These Heavy Duty Self-Clinching Nuts are available as either locking or non-locking, and heat treated or non-heat treated, offering an opportunity to up-grade fastening quality with appreciable cost reduction over weld nuts. Perfect for use in aluminum and controlled steel applications.

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.

Features and Benefits

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.

Thread: Class 2B, MIL - S - 7742; (6H ISO metric)

Locking Performance: Prevailing torque complies with the requirements of IFI-100/107 for Grade B (inch) and ANSI B18:161M Class 9 (metric) locknuts
