Quality metal roofing materials and Precision Fasteners, Inc go hand and hand. In this business, quality is the key. Precision Fasteners was established in 1978 by Ralph Hoffstetter and his son Greg. As industry leaders concerned with quality, Ralph and Greg have both been President of the National Tooling and Machining Association. Father and son have been members of the NTMA for 30 years as well as being 30 year members of the Society of Manufacturing Engineers. Precision Fasteners have a proven, long term dedication to quality. Precision Fasteners stamps and ships precision parts for the Aerospace and Automotive industries as well as the metal roofing industry worldwide. Quality is evidenced by their many awards from both Martin Marietta and Lockheed for superior quality and delivery. Quality in metal roofing materials is another of our specialties. We have designed, developed and tested many of the metal roofing clips and screws that have become industry standards nationwide. Of particular note, for areas with high wind conditions, i.e., hurricanes and other storm areas; We have been involved in many of the tests on metal roofing materials to determine the exact point of “complete failure”. The objective is to meet and exceed the ASTM-E1592 tests. These tests are conducted in an engineering laboratory. Here, a pressure test on the materials is conducted. Roof panels are secured over a metal test chamber and are inflated with pressure and then allowed to relax on the chamber. This is repeated until the roof has a total failure. The engineer can thus determine the wind uplift limits of the roof. The parts from Precision Fasteners have earned UL Classifications and have been extensively tested under ASTM-E1592 guidelines. Many of our Florida customers have also had these clips "Dade Approved" and all of our clips can be manufactured in stainless steel.
