BSO/BSOA/BSOS/BSO4 Series Blind Standoffs

PEM BSO/BSOA/BSOS/BSO4 Series Blind Standoffs are self-clinching standoffs that are made from hardened stainless steel, ideal for clinching into stainless steel sheets. These self-clinching standoffs are pressed into round holes and are mounted permanently into metal sheets as thin as 0.025”/0.63mm. The BSO/BSOA/BSOS/BSO4 standoffs are ideal for applications where mounting, spacing, or stacking of panels, and boards or components are required.
