Self-clinching Standoff Fasteners

PEM micro self-clinching standoff fasteners from PennEngineering are designed for spacing or stacking applications in compact electronic assemblies. Manufactured from 400 Series stainless steel and engineered with very small threads, these RoHS-compliant micro standoff fasteners can be installed into sheet metal as thin as 0.4 mm with maximum hardness up to HRB 88 on the Rockwell B scale. They clinch permanently into place by simply pressing them into a properly sized mounting hole using a punch and anvil. In this way these fasteners become a part of the assembly and provide strong and reusable load-bearing threads.
