Installation

  1. Punch or drill hole in sheet. Do not deburr edges.
  2. Insert pilot pin through hole in sheet and into the anvil as shown.
  3. Squeeze the sheet and pilot pin head between parallel punch and anvil surfaces. Use only enough pressure to seat the pin head flush with the sheet. Punch and anvil may be ordered using the PENCOM part numbers shown in the tables on the next page, or made from hardened tool steel.
  4. A chamfered anvil is required for sheets .060in (1.7mm) thick or less only.

  1. Performance data are reference averages based on commonly reported industry values when all installation speci-fications are strictly followed. Variations such as sheet material type, hardness and thickness; hole diameter; method of hole manufacture; size and location of hole burr if any; and amount of installation load will affect the data. PENCOM strongly encourages testing in the application.
