CSOS-M5-8 is a stainless steel concealed-head self-clinching standoff designed for permanent installation in metal sheets as thin as 1.6 mm, leaving the opposite side smooth and unmarred. It installs using a blind hole with a minimum depth and requires a HAEGER® or PEMSERTER® press with specified tooling. The standoff accommodates a 5.4 mm diameter shank and a 7.93 mm maximum mounting hole diameter, and is intended for use in sheets with hardness up to HRB 70 / HB 125. External threads meet ASME B1.13M, 6h standard. All concealed-head stud and standoff variants share these installation and performance characteristics.
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.
