Sheet Metal Products: Self Clinching fastener solutions for pressing installation

TR Fastenings manufactures and distributes a wide spectrum of sheet metal fastening products that are pressed into pre-punched holes. These include our own branded Hank® Self Clinch fasteners, Hank® Rivet Bushes, and K-Series® Nuts. TR’s sheet metal clinching products provide strong load bearing threads in sheet metal of differing thicknesses.

Installation process overview

Hank® Self Clinch fasteners are designed for installation when both sides of the sheet metal are accessible using a parallel squeezing force, delivered by pneumatic press.

The fast and simple pressing installation process using Hank® Self Clinch studs, nuts, standoffs or panel fasteners creates mutual self deformation between the mating part and the sheet metal fixing. The clinch fastener becomes a permanent part of the sheet metal panel delivering a hugely reliable and strong fixing.


We hold an extensive range of our own branded Hank® Self Clinch products in stock, with access to either our own manufacturers or reliable distributor networks we can also deliver bespoke or product variants at speed.
