Finish 3/4 Inch Square Drive Pan Head Self Drilling Screws # 8 - 18 Thread Black Oxide
1. Description:
The steel self-drilling screw with black oxide finish has a pan head and a square drive. Steel is often used in applications where strength is the primary consideration. The black oxide finish offers mild corrosion resistance and lubricity. The pan head has a flat top and short vertical sides with a rounded top edge. 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.

Phillips pan head self drilling screws have a sheet metal thread with a self driller cutting (TEK) point to pierce through 20 to 14 gauge metals. The higher the TEK number the larger the drill point to pierce heavier gauge metals. The heads use a phillips driver #1, #2 or #3 depending on the size of the screw. These screws are used in the exterior elements.
