IMPORTANT: DO NOT USE IN AN EXISTING HOLE WITHOUT CLEARING THE HOLE WITH A 1/16th INCH DRILL BIT AND ENSURING THE THE PILOT HOLE IS DEEP ENOUGH. For new installations, an adequate pilot hole is required. The recommendation of virtually all screw suppliers is that for a #2 wood screw, a 1/16" diameter pilot hole is REQUIRED. Drilling too small or not deep enough of a pilot hole WILL result in either the screw heads stripping out on soft screws, or breakage at or below the surface for hardened screws (these screws are hardened to prevent the heads from stripping). Do your homework to prevent expensive issues. You can type Pilot Hole For #2 Screw into any search engine and have access to all of the free info you need.
