Concealed-head self-clinching stud, type CHC, for metric thread M5 x 0.8, designed for permanent installation in steel or aluminum sheets as thin as 1.6 mm. The stud provides a reusable thread and allows the back side of the sheet to remain smooth. It requires a blind hole with a diameter of 7.93 mm and a minimum mounting depth of 5.6 mm. The maximum sheet thickness for installation is 20 mm. Installation is accomplished using a PEMSERTER press or standard press, with the flange seated flush to the sheet surface.
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.
