CLA-024-2 - Self-Clinching Nut by PennEngineering ® (PEM ® )

These self-clinching aluminum nuts are engineered to provide strong, load-bearing threads in ultra-thin aluminum panels. When pressed into a properly sized hole, the fastener uses a unique clinching ring that forces the host sheet material to cold flow into an undercut, permanently locking the nut into place. The design features a specialized serrated profile that completely prevents the hardware from spinning or loosening when tightening torque is applied, making it an ideal choice for high-vibration or tight-tolerance electronics enclosures.

High Pushout and Torque-Out Resistance: The cold-flow undercut combined with a serrated clinching ring guarantees maximum mechanical retention against rotation and push-out forces.

Aluminum Compatibility: Specifically designed to install seamlessly into aluminum sheets, ensuring optimal galvanic compatibility and allowing for downstream aluminum anodizing.

Low-Profile Threading: Provides high-strength internal threads in panels that are otherwise too thin to be conventionally tapped.

Clean Fastening Solution: Eliminates the need for welding, tapping, or secondary mounting hardware, reducing manufacturing cycle times.
