PEM Concealed-Head Studs (Unified)

Check up to five results to perform an action.


  • Installed into a blind milled hole where surface opposite stud must remain unmarred. Thread sizes #4 to #10 and M3toM5.
  • These studs and standoffs ensure permanent mounting in metal sheets as thin as .062 in. / 1.6 mm.
  • 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. Center-cutting end mills for hole preparation are available from Penn Engineering. Installation of the concealed-head studs and standoffs is simple using a hollow punch and solid anvil. 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.
