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.

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 type B tip is blunt and intended for use with a pilot hole, often in sheet materials. The lack of a sharp tip is helpful for packaging and handling and in some applications may be helpful for reducing the clearance necessary on the reverse of a fastened panel or for making more thread available on a given length screw.

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.

Galvanization

Galvanization (or galvanizing as it is most commonly called in that industry) is the process of applying a protective zinc coating to steel or iron, to prevent rusting.
