The plain finish 18-8 stainless steel sheet metal screw with 82-degree flat head and Phillips drive has a Type AB point for forming threads in thin metals between 0.015" and 0.050" thick and resin impregnated plywood. The Type AB point has the conical tip of a Type A point with the finer spaced threads of a Type B point. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The flat head has an 82-degree cone shape for use in countersunk holes and a flat top that fits flush with the mated surface. The Phillips drive has an x-shaped slot that accepts a Phillips driver and is designed to allow the driver to slip out of the head to help prevent over-tightening and damage to the thread or fastener.
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.
