Stainless steel concealed-head self-clinching standoffs install permanently in steel or aluminum sheets as thin as 1.6 mm, leaving the opposite side smooth and unmarred. They require a blind hole of specified minimum depth and are installed using a press with matching anvil and punch tooling. These standoffs are recommended for sheet hardness up to HRB 70 / HB 125 and meet ASME B1.1 2B and ASME B1.13M, 6H thread standards. The CSOS series features a two-groove trademark and is available in metric thread sizes including M6. Installation ensures full sealing for ingress protection requirements.
These standoffs ensure permanent mounting in metal sheets as thin as 1.60mm.
The fastener head is locked securely in a blind, milled hole and is able to handle substantial loads. The concealed-head feature allows the side of the sheet opposite installation to remain smooth.
Sheet preparation only requires a milled blind hole to the recommended minimum depth. Center-cutting end mills for hole preparation are available from PennEngineering. Installation of the concealed-head studs and standoffs is simple using a hollow anvil and solid punch. Place the head of the fastener in the hole and insert using any standard press. Displaced sheet metal flows smoothly around the head into the undercut.
