Several common methods such as rivets, screws, and spot welding are used to fasten materials to ductwork. Three types of screws are most often used. The first is self-tapping only and requires a hole to be drilled before the screw can be utilized. The others are both self-tapping but also create their own holes. Self piercing screws have very sharp points which act much like a scratch awl in making a small opening in the steel for the threads to engage and work the sheet metal into a coned threaded hole. These work well for light gage steel.

  • Slotted for easy removal with standard flat driver.
  • Higher head stays in chuck with ease and provides stability during insertion.
  • Serrated Edge to prevent the backing out of the screw.
  • Thread is designed to pull the screw through steel with no strip-out.
  • Heavy zinc-plating for strong corrosion resistance.
  • Pierces through heavier gauges of steel.
  • No metal filings to clog drill chuck.
  • Precision formed point for consistant performance.
  • Super sharp, specially hardened, non-walking point.
