Cup Head Pin GI Steel Perforated Rock wool Pins Insulation Fastener Applied Ductwork

Gold Seal Pins hold the duct liner in place and seal the hole created during insertion. Heat activated gold adhesive on the underside of the washer secures the pin to the liner facing during the welding process.
• Adhesive coating insulates the underside of the washer to allow welding on foil faced insulation.
• Do not store at or above 110F or pins may stick together.
• Gold Seal Pins also feature "dished washers" and precision formed
points to insure consistent penetration of duct liner.
• Gold Seal Pins are designed for use with all FG, RH, PBF, MF, CDMF Pinspotters.

Composition and Materials
The fastener head, shank and point are manufactured from a special carbon alloy steel. A 1" diameter retaining cap fabricated from cold rolled steel is mechanically affixed to the driven end of the fastener.

Industry Standards
PowerPoint Weld pins meet and exceed the latest SMACNA (Sheet Metal and Air Conditioning Contractors National Association) standards, published in their HVAC DUCT CONSTRUCTION STANDARDS 1995, for low and high velocity ductwork. They are used by leading air-conditioning, sheet metal and mechanical contractors for ductwork in commercial buildings.

Corrosion Resistance
PowerPoint Weld pins are plated with .0002" to .0003" of zinc and receive a final chromate dip. This plating exceeds current SMACNA standards for corrosion resistance.

Retaining Cap
The beveled edge retaining cap is sufficient in size and design to depress the surface of the insulation without tearing or cutting it. The cap does not protrude into the air stream to create noise or interfere with air movement in the duct.

Temperature Range
PowerPoint Weld pins function properly over normally accepted operating range of temperatures of 32 degrees F to 250 degrees F and are not adversely affected at temperatures of 0 degrees F to 550 degrees F.
