Hardcast WELD-ONS are manufactured with consistently sharp points to ensure positive contact with sheet metal to which they are to be welded. Produced from a special carbon alloy steel, the point of the welding pin is hardened in a unique cold form process. This hardens the points giving them a steel temper, which unlike other welding pins, will not blunt or flatten when applied.

The sharper point of contact results in a better weld and creates fewer sparks to ignite adhesives or burn substrates. WELD-ONS are easily applied using any conventional portable or automatic resistance welding unit. Cup style washer is designed to sufficiently depress the insulation surface without tearing it.
