The “Penetrator” is a 1/2-in. steel pin for steel framing, drywall, and hvac applications. The company says that the pin can penetrate into a steel beam at the T, and sit flush. Pins for the gas-operated fastening system Trak-It® are assembled on strips of 10 for rapid firing. The manufacturer states that pins and fuel cells for this system are also compatible with competitors’ fastening tools. According to the company, gas-operated systems reduce wasted pins caused by misfire of a powder load, eliminate the need to carry several different strengths of powder loads, and provide a cleaner burn, which keeps the tool cleaner and enhances longevity.
