CSOS-632-12 concealed-head self-clinching standoffs install permanently in sheets as thin as 0.062 in (1.6 mm) to provide reusable internal threads while leaving the opposite surface smooth and sealed. They require a blind hole of 0.213 in diameter and minimum depth, and install using a press with specified anvil and punch tooling. These standoffs are made from 300 series stainless steel with no finish and are rated for installation in sheets with hardness up to HRB 70 / HB 125. Maximum tightening torque is 8.75 lbf·in for cold-rolled steel and 5.000 lbf·in for 5052-H34 aluminum sheet. Installation requires a HAEGER® or PEMSERTER® machine for optimal results.
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.
