The SOS series consists of through-hole, unthreaded, self-clinching standoffs designed for mounting, spacing, or stacking panels in steel or aluminum sheets with a Rockwell B hardness of 70 or less and Brinell hardness of 125 or less. These standoffs install permanently into sheet metal as thin as 0.63 mm using a press-fit method and maintain a minimum edge distance of 0.27 in (6.86 mm). Dimensions such as hole size, barrel diameter, and clinching profile are standardized per series specifications, with lengths varying by orderable code. All variants share the same installation requirements and material compatibility, and are made from hardened stainless steel. The product supports flush mounting and is suitable for non-corrosive environments; optional nickel plating is available for corrosion resistance to meet specific application demands.
These standoffs, which use the proven self-clinching design, install with a squeeze in properly sized round holes - and become permanently mounted in the thin sheet.
Unthreaded standoffs are also available for spacing multi-panel assemblies.
