The fastener head is locked securely in a blind, milled hole and is able to handle substantial loads. The
Concealed-head feature allows the side of the sheet opposite installation to remain smooth.
Sheet preparation only requires a milled blind hole to the recommended minimum depth.
Installation of the concealed-head studs and standoffs is simple using a hollow anvil and solid punch. Place the head of the fastener in the hole and insert
Using any standard press. Displaced sheet metal flows smoothly around the head into the undercut.
