Self-clinching fasteners for stainless steel or aluminium alloy sheets

17 May 2015

microPEM TackPin Type T4 self-clinching fasteners from PennEngineering are suitable for installation into stainless steel or higher-strength aluminium alloy sheets.

They offer tangible benefits over micro screws by eliminating typical screw-related issues, including costly tapping, cross threading, torque control, and vibration back-out.

Design features include an interference fit to minimise hole tolerance issues, a tapered tip to assist in location, and a low-profile head to save space.

Manufactured from 400 Series stainless steel, microPEM Type T4 fasteners install easily by first preparing properly sized mounting holes in the sheet to be attached and the base panel.  After inserting the fastener into these holes, squeezing force is applied to complete the installation process.

The fastener’s head will then hold the top sheet (as thin as 0.2mm) firmly and permanently in place. The base panel can be as hard as HRB 88 or less on the Rockwell B scale and at least 0.89mm in thickness.
