CHC-440-12 - Concealed-Head Stud by PennEngineering ® (PEM ® )

The CHC-440-12 is a high-precision concealed-head self-clinching stud manufactured by PennEngineering® (PEM®).Designed to establish standard external threads in thin metal sheets, this specialized fastener installs seamlessly into a milled blind hole. Because the fastener head stays hidden completely within the cavity, the opposite side of the sheet remains perfectly smooth and unmarred, ensuring flawless exterior styling and paint finishes. Made from durable 300 Series Stainless Steel, it delivers long-term corrosion resistance and creates a reliable, permanent assembly capable of withstanding substantial operating loads without welding.

Concealed-Head Design: Mounts cleanly inside a blind hole to keep the reverse side of the panel flat, closed, and unmarred.

Permanent Self-Clinching Installation: Integrates directly into thin panels using standard press-in action, eliminating complex welding steps.

Premium Material Construction: Fabricated from 300 Series Stainless Steel to provide reliable structural durability and high corrosion resistance.

Substantial Load Capacity: Displaced sheet metal flows smoothly around the head into the undercut to securely support attached components.
