Concealed-Head Stud CHC-032-16 from PennEngineering® is designed for permanent installation in metal sheets as thin as 0.062 inches. This stud provides strong, reusable threads for mating hardware while maintaining a smooth surface on the opposite side of the installation. It requires only a blind milled hole for installation, which can be accomplished using a standard press. The stud meets specific performance data, including a pullout strength of 4,000 lbs in cold-rolled steel and 290 lbs in aluminum. This product is suitable for applications where a clean aesthetic and ingress protection are essential, as it helps to seal the sheet against air, liquid, dust, and other contaminants.
These studs 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.
