The zinc plated steel sheet metal screw with hex washer head and hex drive has a Type B point for forming threads in 0.05"-to 0.050"-thick metals as well as nonferrous castings, plastics, and impregnated plywood. The Type B point has a blunt tip with finer spaced threads than a Type A point. Steel is often used in applications where strength is the primary consideration. The zinc plating offers corrosion resistance and has a reflective appearance. The hex washer head has six flat sides that a wrench can grip to turn from the side, enabling use when there is no space above the head for a screwdriver. The flange acts like a washer to increase the fastener's bearing surface and distribute the clamping force over a larger area, reducing damage to the material being fastened.。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.。 。 。 。
