(2)S4 material code not available for maximum standoff body diameter .165” (4.20mm).

Installation

  1. Prepare correct sized mounting hole in sheet. Do not deburr edges.
  2. Insert standoff through hole in punch side of the sheet and into the anvil as shown.
  3. Squeeze the sheet and standoff head between parallel anvil and punch surfaces. Use only enough pressure to seat the standoff head flush with the sheet.
  4. Anvil with countersink is required for standoff with maximum body diameters.
  5. For installation in stainless steel, the sheet should be annealed and avoid standoff installation next to bends or other highly cold-worked areas. The hole punch diameter should be no greater than .001” (0.025mm) over the minimum recommend- ed mounting hole diameter and kept sharp to minimize work hardening around the hole.

(1) Performance data represents the average result when all installation specifications are strictly followed. Variations in panel hole size, thickness, material and installation method will affect the loads. PENCOM strongly encourages testing in the application.
(2) Torque-out and pull-thru performance may vary depending on the strength and type of screw being used.
(3) Not recommended.
