INSTALLATION 

  1. Punch or drill hole in sheet a minimum distance of .37in (9.4mm) from the hole center to edge of sheet. Do not deburr edges.
  2. Insert the ball stud through hole in sheet and into the anvil as shown.
  3. Squeeze the sheet and ball stud head between parallel punch and anvil surfaces. Use only enough pressure to seat the ball stud head flush with the sheet. Punch and anvil should be made from hardened steel.
