Application
1: Position insulation
2: Press cup head pin through insulation
3: Weld in place to complete installation
Cupped head pins
1. Cupped head insulation pins is a insulation fastener which is used to fasten the insulation materials to sheet metal
of air duct, other heating, ventilating or air conditioning.
2. A fabricated part made up of a weld pin and a staked on retaining washer,it is usually applied with a capacitor
discharge stud welder.
3. The method of application is to place the insulation onto a metal surface, push the Cup Head weld pin through the insulation,
and weld affix (mount) the entire fabrication in one step. Now it is widely accepted as labor saving fasteners
in the thermal and acoustical insulation markets for use in industrial and commercial applications.
