Weld Pins

Weld pin insulation fasteners are insulation pins that are applied with welding equipment. Weld pins are commonly used as insulation fasteners in conjunction with washers. Once the pin is welded in place, insulation is impaled over the pin and held in place with an insulation washer. Weld pins are available in various sizes and gauges in aluminum, bi-metallic, low carbon steel, mild steel, and stainless steel. Browse our selection below.
