1. Beveled Edge Cap
Prevents tearing of duct liner

2. Faster Welds
Forged diamond point design creates more electrical resistance for faster welds.

3. Better Plating
Zinc and Chromate plating exceeds SMACNA standards and gives a more professional appearance.

4. Reduced Down Time
Consistent point quality reduces frequency of machine adjustments.

5. Stronger Welds
Hardened steel point assures positive electrical contact for complete sheet to pin fusion.

6. Applied with Standard Equipment
Easily applied with Gripnail's Automatic Pin Welder or most standard hand held or hopper fed resistance welders.

Item: Cup Head Weld Pins

Application: used for fastening insulation material on metal surface

Step:
