Desription from GripNail :
"A Gripnail is a unique mechanical fastener used to attached insulation to sheet metal. It was specifically designed to fasten acoustical duct liner to the inside of heating, ventilating and air conditioning ductwork. This operation generally takes place when the ductwork is being manufactured.
How Gripnails Work
Gripnails are driven through the insulation and into the sheet metal with controlled impact. The hardened tapered teeth of the fastener (see photo below) bite into the sheet metal without puncturing. A hardened steel back-up plate is required to properly set the teeth of the Gripnail in the sheet metal.
The impact of Gripnail when driven into sheet metal causes tapered teeth at it's tip to close, biting into and holding the softer metal but not puncturing it.
A permanent attachment is formed with the hardened steel fastener "nailed" to the sheet metal. A pre-attached cap holds the duct liner firmly in place.
Gripnail fasteners withstand pulls up to 120 lbs., far exceeding SMACNA application standards. Extensive tests also demonstrate Gripnail fasteners have superior corrosion resistance, surpassing SMACNA's 96 hours saltspray test"
