PEM® self-clinching standoffs, which use the proven self-clinching design, provide

ideal solutions for applications where mounting, spacing or stacking of panels,

boards or components are required. Pressed into round holes, these fasteners

mount permanently into metal sheets as thin as .025” / 0.63 mm.

Specially designed SO4™, BSO4™ and TSO4™ standoffs are made from hardened

stainless steel and are ideal for clinching into stainless steel sheets. An optional

nickel plating is now available if product is expected to be used in a corrosive

environment.

For more information on the proper use of PEM® self-clinching standoffs, check our

website for Tech Sheet PEM® - REF/Standoff Basics.
