  1. Performance data represents the average result when all installation specifications are strictly followed. Variations in sheet hole size, thickness, material and installation method will affect the loads. PENCOM strongly encourages testing in the application.
  2. Not recommended.

 

Installation

  1. Punch or drill hole in .040in (1.02mm) minimum thick sheet a distance of .33in (8.4mm) minimum from hole center to edge. Do not deburr hole 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 surfaces. Use only enough pressure to seat the standoff head flush with the sheet. Punch and anvil may be ordered using PENCOM part numbers TL1287 and TL1288, respectively, or made from hardened tool steel.
