Galvanized Steel Cup Head Insulation Pins 2.7mm Applied With A Capacitor Discharge Stud Welder

Cup Head Insulation Pins are mild steel fabricated parts consisting of a weld pin and a staked-on speed clip or retaining washer. The most common configuration features a mild steel weld nail with a galvanized-coated mild steel retaining washer.

• Beveled edge washer: Prevents cutting of insulation material
• Customizable sizes: Washer and nail dimensions can be tailored to requirements
• Faster welds: Forged diamond point design creates more electrical resistance
• Superior plating: Zinc and copper plating exceeds SMACNA standards
• Reduced downtime: Consistent point quality minimizes machine adjustments
• Strong welds: Hardened steel point ensures complete sheet to pin fusion
• Compatibility: Works with automatic pin welders and standard resistance welders

These pins are typically applied using a capacitor discharge stud welder. The installation process involves placing insulation onto a metal surface, pushing the pins through the material, and welding the entire assembly in one step. They are widely used as labor-saving fasteners in thermal and acoustical insulation applications.
