HVAC Air Duct System Copper Plated Mild Steel Round Cupped Head CD Weld Nails

HVAC Air-Duct System Copper Plated Mild Steel Round Cupped Head CD Weld Nails

Description details of round cupped head cd weld nails

Cup Head Capacitor Discharge CD weld nails are manufactured to be a single robust fastener. The precision attachment of cap and shank allows for better contact when welding. The optional protected adhesive on the underside of the cap acts as a superior insulator over traditional paper washers. The coating substantially reduces arcing when fastening foil face insulation, while the forged diamond point defines the standard of sharpness to cleanly pierce the toughest insulation.
