CLSS-M5-1 - Self-Clinching Nut by PennEngineering ® (PEM ® )

The PEM® CLSS-M5-1 is a high-strength self-clinching nut engineered to establish permanent, durable load-bearing threads in thin steel and aluminum panels. Fabricated from high-grade 300 Series Stainless Steel, this metric fastener provides superior corrosion resistance, making it an excellent choice for electronic cabinets, medical instruments, and demanding automotive assemblies. When integrated using standard parallel squeezing forces, the host sheet material cold-flows precisely into the nut's specialized undercut, creating an unyielding joint with exceptional pushout and torque-out resistance while entirely avoiding the panel warping, surface blemishes, and thread stripping common with traditional welding methods.

Elite Pushout and Torque-Out Resistance locks the fastener permanently into the host chassis to easily withstand immense rotational assembly torque and heavy axial pulling loads.

300 Series Stainless Steel Construction offers heavy-duty structural durability combined with dependable, long-term defense against environmental and atmospheric corrosion.

Passivated Quality Finish satisfies rigid manufacturing cleanliness criteria to optimize surface integrity and extend overall component longevity.

Distortion-Free Clinch Installation utilizes an efficient, mechanical press process that eliminates the operational costs, thermal stresses, and safety concerns associated with manual welding or tapping.
