Gripnail

Gripnail specializes in fastening solutions focused on lean and cost-effective manufacturers.  

Gripnail Fastening Systems was founded in 1966 in East Providence, Rhode Island by Peter and Peggy Hallock with the help of Peter’s father, renowned inventor Robert Hallock. The product? A revolutionary mechanical fastener that  bites into metal  to form a solid metallurgic bond. The Gripnail would go on to be the standard mechanical fastener for the HVAC duct-lining industry. Not long after that, Gripnail developed a patented line of fasteners and application equipment for the OEM industry. This line of products would lead to broader international success for Gripnail.
