INSULATION FASTENERS: "SURE - FIRE" (CD)

The Sure Fire Weld Pin is a capacitor discharge weld Pin in a Low Carbon Steel or Stainless Steel that is ideal to apply with heavy duty pin welding or capacitor discharge stud welding equipment. Manufactured with a heavy duty Capacitor Discharge weld tip and flange, the Sure Fire Weld Pin is popularly used as an insulation fastener, in combination with self locking washers (or speed clips) to retain insulating material. The unique enlarged capacitor discharge weld tip with flange and large diameter CD weld equipment for stud welding make this an economic and cost-saving metal fastener when stud welded in place. A main advantage of the Sure Fire Weld Pin is its ability to be properly welded through surface contamination without preparation of the area to be pin welded.
