Concealed-Head Studs - Types CHA,CFHA,CHC,CFHC - Metric
Ensure secure and permanent mounting in thin metal sheets with these concealed-head studs. Designed for sheets as thin as 1.60mm, they feature a locked fastener head in a blind, milled hole, capable of handling substantial loads. The concealed-head design maintains a smooth sheet surface post-installation. Sheet preparation is simple, requiring only a milled blind hole to recommended depth. Installation is effortless with a hollow anvil and solid punch, as displaced sheet metal flows smoothly around the head into the undercut. Made from 300 Series Stainless Steel with a Passivated finish, these studs offer both durability and corrosion resistance for a wide range of applications.
