18-8 Stainless Steel Sheet Metal Screw, Plain Finish, Oval Head, One-Way Drive, Type AB, 1-1/4" Length, #8 Threads, Made in US (Pack of 25)

The plain finish 18-8 stainless steel sheet metal screw with oval head and one-way 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. The 18-8 stainless steel material provides strength and offers good corrosion resistance in many environments. The material may be slightly magnetic. The oval head is cone shaped for a flush fit in a countersunk hole and has a slightly rounded top that sits above the mated surface. The one-way drive has a sloped S-shaped slot that enables installation with a standard slotted driver but resists tampering by requiring a special tool for removal.

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.
