Alloy Steel Sheet Metal Screw, Black Oxide Finish, Button Head, Pin In Head Hex Drive, Type AB, 1/2" Length, #10 Threads, Made in US (Pack of 50)

The black oxide alloy steel sheet metal screw with button head and pin-in-head drive has a Type AB point for forming threads in thin metals between 0.015" and 0.050" thick and resin impregnated plywood, and is made in USA. The Type AB point has the conical tip of a Type A point with the finer spaced threads of a Type B point. Alloy steel is often used in applications where strength is the primary consideration. The black oxide finish offers mild corrosion resistance and lubricity. The button head has short vertical sides similar to a pan head screw, but has a low-profile rounded head instead of a flat top. The large bearing surface of the head reduces the chance of the screw embedding in the fastening material. The pin-in-head hex drive has a hexagonal indentation with a center pin that resists tampering by requiring a special driver to tighten or loosen the screw.Sheet metal screws, a type of self-tapping screw, have threads down the entire length of the shank for tapping and fastening thin material. The point style determines the type of material the screw can be used on, such as metal, wood, or plastic. These screws commonly have a sharp point that helps penetrate the material.
