Stainless steel 18-8 hex socket cap head self tapping screw
Product Description
When you are looking for fasteners, you are trying to evaluate the situation and pick the best way to put materials together. Fastening one or more pieces of light, medium, or heavy gage sheet metal together may require the use of adhesives, riveting, or self-tapping screws. If an application requires access or several layers, tapping screws maybe the best option.
These screws either come with a blunt, flat, sharp or piercing tip. Sharp-tipped self-tapping screws drill their own holes in softer wood and plastic. However, it is helpful to drill a pilot hole when working with harder material. When drilling a pilot hole, make sure to use a smaller bit than the screw so it may still serve its purpose.

Self-Tapping
The ability of a screw to advance when turned, while creating its own thread versus, say, machine screws which require a pre-threaded nut or other female insert. Self-Tapping screws can cut their own threads as the screw is driven in to the material. They function by having a cutting edge which drills away the material, making a tiny hole for the screw to go into. This has nothing to do with the point of the screw but has everything to do with the threads which are designed to cut through the material.
Raw Material: Stainless steel
As we all know, stainless steel’s resistance to corrosion and staining, low maintenance, and familiar lustre make it an ideal material for many applications.
The most widely used austenite steel is the 304, also known as 18/8 for its composition of 18% chromium and 8% nickel.304 may be referred to as A2 stainless (not to be confused with AISI grade A2 air hardening alloy tool steel containing about 5% chromium).
