  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. Flare the retainer shank into the sheet countersink using light pressure. Punch flare angle should match the sheet hole countersink angle. Anvil and punch should be made from hardened tool steel or may be ordered using the PENCOM part numbers shown in the tables below.
