While some variations of material are available, the most popular style Cup Head Weld Pin is a mild steel weld nail with a galvanized-coated mild steel retaining washer.
This product is usually applied with a capacitor discharge stud welder such as the Cutlass Pinto Pin/Stud Welder. Cup Head pins are widely accepted as labor saving fasteners in the thermal and acoustical insulation markets.
