Concealed-Head Studs - Types CHA,CFHA,CHC,CFHC - Metric
Ensure secure and permanent mounting in metal sheets as thin as 1.60mm with these concealed-head studs. Designed for effortless installation, they feature a locked fastener head in a blind, milled hole, capable of withstanding substantial loads while keeping the sheet surface smooth. With sheet preparation requiring only a milled blind hole to the recommended depth, installation is a breeze using a hollow anvil and solid punch. The concealed-head design offers a seamless finish, with displaced sheet metal flowing smoothly around the head into the undercut. Perfect for applications where both strength and aesthetics are paramount.
