Carbon Steel Phillips Countersunk Head Wood Screw with Sharp Tip
As construction materials and techniques evolve, fastener design keeps pace with the changing technology.There are many sizes and styles of nails available.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.
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.
Raw Material: Carbon Steel
Carbon steel is a steel with carbon content up to 2.1% by weight.
The purpose of heat treating carbon steel is to change the mechanical properties of steel, usually ductility, hardness, yield strength, or impact resistance.
Plating and Coatings
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). Screws are plated and/or coated for three reasons.
Ningbo Oukailuo Hardware Co., Ltd. was founded in 1999 and is a leading fastener manufacturer. Company passed ISO9001:2015 quality management system certification, and has ROHS, SGS certificate. Our main export markets are North America, Europe, Oceania, Korea, etc.
We have our own heat treatment shop, electroplating shop, Ruspert workshop. The heat treatment process is very important for product hardness, and our technology can ensure it. Electroplating includes galvanization, yellow zinc, black zinc, and green zinc. All galvanization meets ROHS. Salt spray time can be up to 96 hours. Ruspert can do most of the colors. The salt spray time can be 500 hours and 1000 hours.
