CFHC-M5-10 concealed-head self-clinching studs install permanently in steel or aluminum sheets as thin as 1.6 mm to provide reusable M5x0.8 threads, leaving the opposite sheet surface smooth. Installation requires a blind hole with a minimum depth of 7.93 mm and a hole diameter of 5.6 mm, and the flange must be flush with the sheet surface. These fasteners are made of stainless steel with a passivated finish and are rated for use in materials with hardness up to HRB 70 / HB 125. They install using a PEMSERTER® press or equivalent with anvil and punch tooling specified for this thread size.
These studs 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.
