CSOS-M4-10 is a stainless steel concealed-head self-clinching standoff designed for permanent installation in metal sheets as thin as 1.6 mm, providing a smooth, unmarred surface on the opposite side. It requires a blind hole with a minimum diameter of 4.03 mm and a minimum depth of 7.37 mm for proper installation. The standoff accepts M4 threads and is compatible with 300 series stainless steel or aluminum sheets of hardness HRB 70 or less, or HB 125 or less. Installation is performed using a PEMSERTER® or HAEGER® press with specified tooling. The product meets ASME B1.13M, 6g thread specifications and is passivated per ASTM A380.
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.
