Concealed-Head Studs - Types CHA,CFHA,CHC,CFHC - Metric
These studs ensure permanent mounting in metal sheets as thin as 1.60mm, with the fastener head securely locked in a blind, milled hole to handle substantial loads. Featuring a concealed-head design, they maintain a smooth sheet surface post-installation. Sheet preparation is easy with a milled blind hole, and installation is simple using a hollow anvil and solid punch. Displaced sheet metal flows smoothly around the head into the undercut, providing a seamless finish for your application.
