Concealed-Head Studs - Types CHA,CFHA,CHC,CFHC - Unified
Ensure secure mounting in metal sheets as thin as .062 inches with these concealed-head studs. Designed for permanent installation, they feature a fastener head that is locked in a blind, milled hole, providing reliable strength for substantial loads. The concealed-head design maintains a smooth surface on the opposite side of the sheet, offering a clean finish. Installation is straightforward, requiring only a milled blind hole to the recommended depth. Using a hollow anvil and solid punch, insert the stud with ease using a standard press. The displaced sheet metal flows smoothly around the head into the undercut, ensuring a secure attachment for various applications. Made of 300 Series Stainless Steel with a passivated finish, these studs are not only durable but also compliant with RoHS regulations. Explore the animation for a visual guide on installation.
