Hardness 8.8 Construction Wood Screws Stainless Steel Hex Head Wood Screws

Carbon steel hex head wood screw for construction Hardness 8.8

Product Description

Wood screws are handy for quickly building jigs and clamping forms, joining cabinet and furniture parts, mounting hardware and trim, and much more. Screws form strong connections between parts made from solid wood, plywood and other sheet goods without the need for cut joinery.

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

In the final step of manufacturing, most steel wood screws receive some kind of plating (a metallurgical process done to bare metal screws) or coating (applied to either bare metal screws or already-plated screws).

Galvanising protects the underlying iron or steel in the following main ways:

• The zinc coating, when intact, prevents corrosive substances from reaching the underlying steel or iron.
• The zinc serves as a sacrificial anode so that even if the coating is scratched, the exposed steel will still be protected by the remaining zinc.
• The zinc protects iron by corroding first. For better results, application of chromates over zinc is also seen as an industrial trend.

How To Use Wood Screw

You won't need to bore a pilot hole, because these screws have serrated threads toward the tip that cut away wood like a saw. That also means you can drive them close to the end of a board without it splitting. On the underside of their bugle heads are ridges that cut a nice, neat countersink. The wood screw also add a cut thread at the tip that helps get the screw started and another thread at the shank that enlarges the hole slightly to further reduce splitting. Because of all this clever engineering and because these fasteners are made of hardened steel, they won't shear off under normal use.
