The plain finish 18-8 stainless steel sheet metal screw with pan head and slotted drive has a Type A point for forming threads in thin metals between 0.015" and 0.050" thick and resin impregnated plywood. The Type A point has a conical tip and spaced threads. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The pan head has a flat top and short vertical sides with a rounded top edge. The slotted drive has a linear slot for use with a flat-blade driver.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.
