CHC-632-8 - Concealed-Head Stud by PennEngineering ® (PEM ® )

These self-clinching studs provide a high-strength, permanent mounting solution within thin metal sheets while ensuring the side opposite the installation remains completely smooth. By locking the fastener head securely inside a blind, milled hole, this design allows the final assembly to meet rigorous physical demands without breaking through the exterior sheet face. When pressed into position using a standard press with a hollow anvil and solid punch, the displaced metal flows smoothly into the undercut, ensuring the fastener can successfully handle substantial loads.

Concealed-Head Profile: Installs cleanly into a blind, milled hole to preserve a completely smooth, flush surface on the reverse side of the panel sheet.

Surface Integrity Protection: Safeguards the exterior surface from being unmarred, punctured, or compromised during hardware installation.

High Load Capacity: Employs a self-clinching undercut that locks tightly under press compression to reliably support significant pull-out and torque loads.

Permanent Hardware Integration: Quickly and simply pressed into place using standard installation equipment to create robust, non-loosening external threads.
