Features

  • Join two sheets together by simply sliding the top panel into place to precisely space removable components.
  • Use several TJ Key-Loc™ Standoffs with one standard threaded standoff to prevent unwanted top sheet movement, and reduce installation time and excess hardware.
  • Self-clinching design installs easily and permanently with a flush appearance on the back of thin panels.
  • Available in a wide variety of sizes with custom dimensions by request.

Installation

  1. Punch or drill hole in sheet. 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 TL1345, respectively, or made from hardened tool steel.
