Groomed for ever-shrinking designs, the PEM micro self-clinching standoff fasteners for spacing or stacking applications enable quicker assembly of devices ranging from hand-held consumer electronics to medical equipment. The components are manufactured from 400 Series stainless steel with threads as small as M1.0/#00 and in lengths as short as 2 mm. They can be installed into sheet metal, including 300 Series stainless steel, as thin as 0.4 mm with a maximum hardness up to HRB 88 on the Rockwell “B” scale. The micro standoffs clinch permanently into place by pressing them into a properly-sized mounting hole using a punch and anvil until the fastener’s head is flush with the sheet. Upon installation, they become a permanent part of an assembly, will not loosen or fall out, and provide reusable load-bearing threads. PENNENGINEERING, Danboro, PA. (800) 237-4736.
