SAF8x2 - 1/4" Head x #8 x 2" 500 Pack, Self-Piercing and Self-Threading Screw

Description

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.

Features:
  • 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.
