Small Parts 0820KQT Steel Self-Drilling Screw, Zinc Plated Finish, Flat Trim Head, Square Drive, #2 Drill Point, #8-18 Thread Size, 1-1/4" Length (Pack of 50)

The steel self-drilling screw with zinc plating has a flat trim head and a square drive. Steel is often used in applications where strength is the primary consideration. The zinc plating offers corrosion resistance and has a reflective appearance. The flat trim head has a flat top and is smaller than other screw heads for less visibility when installed. The square drive resists slippage better than a Phillips or slotted drive.Self-drilling screws, a type of self-tapping screw, are threaded fasteners that drill their own hole and thread it as they are installed. Usually only recommended for use with metal, self-drilling screws are available with wings that enable use when fastening wood to metal. The drill point length should be long enough to penetrate both materials being fastened before the threading portion reaches the material.
