Concealed-Head Studs - Types CHA,CFHA,CHC,CFHC - Metric
These studs ensure permanent mounting in metal sheets as thin as 1.60mm. The fastener head is locked securely in a blind, milled hole, capable of handling substantial loads while maintaining a smooth surface on the opposite sheet side. Sheet preparation is simplified, requiring only a milled blind hole of recommended depth. Installation is straightforward using a hollow anvil and solid punch, with displaced sheet metal flowing smoothly around the head into the undercut. A reliable solution for concealed-head fastening in various applications.
