Capped Capacitor Discharge (CD) Weld Pins are used to fasten insulation to the inside
of sheet metal air ducts. These fasteners are usually applied when the ductwork is being
fabricated.
The fasteners have been specifically designed to work with all currently available duct liners
and Capacitor Discharge (CD) type welding application equipment. Capped CD Weld Pins are
available for 12,25,38,50,75 and 100mm insulation.
Item: 1-1/8" Capped Capacitor Discharge (CD) Weld Pins Material: Galvanized steel Head Size: 30mm

![]() | 1. This product is usually applied with a capacitor discharge stud welder. 2. The method of application is to place the insulation onto a metal surface, push the CD weld pins through the insulation, and weld affix (mount) the entire fabrication in one step. 5. Cup head CD weld pins are widely accepted as labor saving fasteners in the thermal and acoustical insulation markets primarily for commercial type insulation applications. |
