Installation & Performance

  1. Prepare correct sized mounting hole in sheet. Do not deburr hole edges.
  2. Insert fastener in recessed anvil, locate sheet hole over captive screw shank and center punch over screw thread.
  3. Squeeze the fastener between concentric and parallel anvil and punch surfaces. Use only enough pressure to seat the reatainer shoulder flush with the sheet. Anvil and punch should be made from hardened tool steel or may be ordered using the PENCOM part numbers shown in the tables below.
