Clinch fastener suits thin metal assemblies

PennEngineering tells us that its PEM self-clinching concealed-head studs and standoffs can be installed permanently in steel or aluminium sheets as thin as 1.6mm to provide strong and reusable threads for mating hardware in a wide range of thin-metal assembly applications.

The product's concealed-head feature contributes particular design benefits by allowing the side of the sheet opposite installation to remain smooth and untouched. This feature additionally serves to satisfy applications where the sheet must remain completely sealed from air, liquid, dust, gases, or other potentially infiltrating elements.

The aluminium or stainless steel studs are available in a wide variety of thread lengths in M3 through to M5 and in Imperial equivalents. Stainless steel standoffs are offered in M3 to M6 in lengths from 4mm to 25mm. These fasteners are RoHS-compliant and some stud types meet NASM63540 specifications.

Detailed specifications and free part drawings can be accessed from the Internet.
