CFHC-M5-12 concealed-head self-clinching studs install permanently in aluminum or steel sheets as thin as 1.6 mm to provide reusable M5 x 0.8 threads, leaving the opposite side smooth and sealed. They require a blind hole of 5.6 mm diameter and a minimum installation depth of 7.93 mm. Installation is performed with a press using a hollow anvil and solid punch, ensuring the flange sits flush with the sheet surface. These studs are made of stainless steel with a passivated finish, rated for use in sheets with hardness up to HRB 70 or HB 125. The part complies with standard thread specifications ASME B1.1 and ASME B1.13M, 6g.
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.
