Installation
- Punch or drill hole in sheet. Do not deburr edges.
- Place guide pin receptacle nut into the anvil hole and locate sheet hole over the guide pin receptacle nut shank as shown. Ensure that the receptacle nut is installed in the punch side of the sheet.
- Squeeze the sheet and guide pin receptacle nut between parallel punch and anvil surfaces. Use only enough pressure to sea t the receptacle nut shoulder flush with the sheet. Over installation may damage the receptacle nut and prevent use with guide pin. Pen com recommends checking the nut inside diameter with a pin gauge after installation.
