Installation

  1. Punch or drill hole in sheet. Do not deburr edges.
  2. Insert standoff through hole in sheet and into the anvil as shown.
  3. Squeeze the sheet and standoff head between parallel punch and anvil sur faces. Use only enough pressure to seat the standoff head flush with the sheet.
  4. Anvil with countersink is required for installation in sheets with thickness .025” to .032″ (0.63mm to 0.81mm). Anvil with countersink is not required for installation in sheets with thickness greater than .032″ (0.81mm). Punch and anvil should be made from hardened steel.

(1) Performance data represents the average destructive result for standoffs only when all installation specifications are
strictly followed. Variations in panel hole size, thickness, material and installation methods will affect the loads. Pencom
strongly encourages testing the application.
