INTRODUCTION

Clinch fasteners are used in conjunction with stamped or fabricated metal assemblies. They are used extensively in both automotive and non-automotive applications They are captive-style fasteners that – upon installation – become a permanent part of the mating assembly. 

Various clinch fastener designs are available. Popular options include traditional self-clinching fasteners and Anchor® Rivet Bushes.

Design considerations include the required push-out and torque performance, mating material type (including ductility, hardness, and thickness), space constraints and/or proximity to material edge. Clinch fasteners offer many benefits including mitigating the need for loose hardware, facilitating final assembly, and ensuring ease of repair and/or disassembly.

PSM SELF CLINCHING NUTS

Threaded fasteners which incorporate a knurled platform and a groove. This platform, when embedded in the sheet, causes the displaced material to flow evenly into the groove of the fastener to give a positive retention.
