Cold Formed Self-Clinching Nuts


  • Heat treated, zinc plated carbon steel
  • Improved strength
  • Cost savings
  • Available in a broad selection of thread and shank length sizes

We’ve heavily invested in improving manufacturing and quality processes to bring a higher standard of performance to our customers.

PENCOM announces our new product line for self-clinching nuts. Self-clinching nuts are a key component in the sheet metal industry and provide reusable, robust threads in thin carbon steel or aluminum sheets. These nuts are much more resistant to any strain incurred during the installation process. PENCOM’s new manufacturing and quality processes make these parts hard to beat.


  1. Prepare correct sized mounting hole in sheet away from bends or other highly coldworked areas. Do not deburr hole edges.
  2. Insert nut into recessed anvil and place sheet hole over the nut shank as shown with hole punch side of sheet against the nut.
  3. Squeeze the sheet and nut between parallel anvil and punch surfaces. Use only enough pressure to seat the nut shoulder flush with the sheet.
  4. In the application, install screw from the shank side of the fastener so that the head side of the nut is drawn toward the sheet.
