This mainly refers to the chemical composition of screws, screws, and wires in the screw industry. ,High-carbon steel. In this way, we can electroplate the screws according to customer requirements, such as white nickel plating, white zinc plating, color zinc plating, blue zinc plating, Dacromet plating, environmentally friendly color zinc plating, green, blue, zinc, etc.

Simply put, the circle of screws around the wires of the internal label brand manufacturers, the screw wire specifications, the screw wire rod, the production screw line furnace number or batch number F and some also indicate the number of screw lines. The main chemical components of steel are: carbon, manganese, phosphorous, sulfur, silicon, copper, and aluminum, characterized in that the content of Al Wafer Head Cement Board Screw and Cu is as low as possible. What is the processing and forming of screws: Material, iron, aluminum, plastic, etc.

And weight etc. Packing: Pack the products in boxes/boxes according to standards or customer requirements. Annealing: Eliminate wire processing stress and improve ductility. Some customers require a relatively high level of strength for screws..

Under normal circumstances, our screw manufacturers start to finish with the head machine screws. Pack some good screws in the bag, and write the corresponding screw type screw, screw type, thread specification, screw size, and screw plating on each package.

This is convenient for customers. This is a screw that requires a relatively high degree of hardness, so we have to work hard on the screws. Tooth shape, self-tapping teeth, mechanical teeth, wooden teeth, etc.
