Small Parts 0806BPU188 18-8 Stainless Steel Sheet Metal Screw, Plain Finish, Undercut 82 degrees Flat Head, Phillips Drive, Type B, #8-18 Thread Size, 3/8" Length (Pack of 100)

The plain finish 18-8 stainless steel sheet metal screw with undercut 82-degree flat head and Phillip drive has a Type B point for forming threads in 0.015"-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. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The undercut flat head has a flat top with an 82-degree cone-shaped bearing surface and is undercut to a lower head height for use in shallow countersunk holes. 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.
