Weld-Ons™ Insulation Fastener, 1 in Dia, Carbon Steel

Weld-Ons are manufactured with consistently sharp points to ensure positive contact when welded to sheet metal. Produced from 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 washers are designed to Sufficiently depress the insulation surface without tearing it.
