First, prepare the wire for the production of screw fasteners. Screw wires of different specifications are also different. There are different sizes and thicknesses.
After selecting the wire, the screw fasteners should be headed first. There are many head types for screw fasteners, such as the commonly used countersunk, hexagonal, round, pan, cup, and flat heads. Generally, it is produced by single-mode machine, multi-mode machine, or clamping machine.

The overall appearance of the screw fasteners is headed and the teeth are rubbed. Due to the needs of different users, the screw fasteners sometimes need to be surface treated or cleaned. At this time, electroplating equipment is needed.
After the screw fasteners are electroplated, the screw production steps have basically been completed, but a series of inspection steps are required before the screws are shipped. Salt spray testing machine, nail selection machine, etc.,
Packed and shipped according to different requirements of customers, such as how many screws in a pack, independent packaging or whole packaging. Is there a need for isolation between screws and screws?
