1. Position insulation
2. Press cup head pin through insulation
3. Weld in place to complete installation

1. Cupped head insulation pins are fasteners used to secure insulation materials to sheet metal of air ducts and HVAC systems
2. Consists of a weld pin with a staked on retaining washer, typically applied with a capacitor discharge stud welder
3. Application involves placing insulation on metal surface, pushing the pin through, and welding the entire assembly in one step
4. Widely accepted as labor-saving fasteners in thermal and acoustical insulation markets for industrial and commercial applications
