CSOS-832-6 concealed-head self-clinching standoffs install permanently in steel or aluminum sheets as thin as 0.062 in. to provide threaded mounting points while leaving the opposite side smooth and sealed. They require a blind hole with a diameter of 0.179 in. and minimum depth of 0.290 in. for installation using a PEMSERTER® or HAEGER® press. The fastener is made of stainless steel and meets ASME B1.1 2B thread specifications. Performance data confirms a maximum installation force of 4,000 lbf in cold-rolled steel and 3,000 lbf in 5052-H34 aluminum, with a maximum torque of 18 in-lbf. The design satisfies ingress protection requirements by sealing the mounting hole.
These standoffs ensure permanent mounting in metal sheets as thin as .062 in.
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.
