CSOS-440-8 stainless steel concealed-head self-clinching standoffs install permanently in steel or aluminum sheets as thin as 0.062 in. to provide reusable threads while leaving the opposite side smooth and unmarred. They require a blind milled hole to the recommended size and depth and are installed using a press with a hollow anvil and solid punch. These standoffs meet ASME B1.1 2A/2B threaded standards and are passivated for corrosion resistance. They are designed for use in materials with hardness up to HRB 70 or HB 125. Installation tooling is available for this thread size, with PEMSERTER® part number 970200008300 and HAEGER® anvil part number H-109-4/M3L.
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.
