Carbon Steel Blue Zinc Hex Head Self Tapping Screw
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.
Self-tapping screws have a wide range of tip and thread patterns, and are available with almost any possible screw head design. Common features are the screw thread covering the whole length of the screw from tip to head and a pronounced thread hard enough for the intended substrate, often case-hardened.
The sharp-tipped screws are designed for drilling their own hole into softer materials such as wood and plastic so they don't need a pilot hole.
A flanged head can be any of the above head styles (except the countersunk styles) with the addition of an integrated flange at the base of the head. This eliminates the need for a flat washer.
Raw Material: Carbon Steel
Carbon steel is a steel with carbon content up to 2.1% by weight.
As the carbon percentage content rises, steel has the ability to become harder and stronger through heat treating; however, it becomes less ductile. Regardless of the heat treatment, a higher carbon content reduces weldability. In carbon steels, the higher carbon content lowers the melting point.
The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance.
Case hardening processes harden only the exterior of the steel part, creating a hard, wear resistant skin (the "case") but preserving a tough and ductile interior.
