Concealed-Head Studs - Types CHA,CFHA,CHC,CFHC - Metric
These concealed-head studs ensure secure mounting in thin metal sheets as little as 1.60mm thick, with the fastener head locked firmly in a blind, milled hole to withstand substantial loads. Their hidden design maintains a smooth sheet surface post-installation, requiring only a milled blind hole for preparation. Installation is straightforward using a hollow anvil and solid punch, with displaced sheet metal flowing seamlessly around the head for a neat finish. Crafted from durable 300 Series Stainless Steel with a passivated finish for added protection, these studs offer reliable performance in various applications while complying with RoHS standards.
