You know how easy it is to overdrive a screw and drive it too deep, especially when working with MDF or particleboard! PowerHead Screw's unique design completely eliminates this problem while offering two installation options! Above the surface: Drill the PowerHead into position so that the entire head sits on the surface of your material. Below the surface: In combination with an impact driver drill, the PowerHead Screw has been engineered with nibs underneath the large 9/16" head to cut through your material and allow your screw to sit perfectly flush with the material surface. The type 17, self-drilling auger point allows these screws to be driven into most woods without a pilot hole, and wide threads provide greater holding power. #8 gauge; zinc plated; 9 TPI.
