Standard Clinch Nuts provide permanent, load-bearing internal threads in thin sheet metal and other low-section assemblies. Series C heat-treated carbon steel with clear zinc finish is suited to materials up to HRB-80, while Series CS 300-series passivated stainless steel suits materials up to HRB-70. Installed squarely into a prepared hole using squeezing force, they deliver reliable pushout and torque-out resistance without welding, tapping or loose hardware, improving production efficiency and joint consistency.
