Could long screw and bolts be surface treated?

Generally speaking, when we do screw accessories, will choose to do the surface treatment, one is to look good on the surface, two is to increase the anti-corrosion, anti-rust ability of the screw, to extend the service life of the screw. Can the long screw and bolts be surface treated?

The difference between the long screw and the ordinary screw is that its length is much longer. If the length of the screw is too long, it will not be put into the electroplating pool during the surface treatment, or if the screw is too long, it will be easy to bend. In this case, it will be difficult to do the surface treatment.

However, long screw and bolts can indeed be surface-treated. If the screws are easy to bend, it is recommended to change to stainless steel, direct color clear or do hanging plating, so that it is not easy to bend. If it is made of iron, zinc plating, nickel plating and other surface treatment, according to the length of the different, the use of electroplating method is also different.

If you want to produce long screw and bolts, and want to do surface treatment, welcome to come to consult the Shi Shi Tong screw manufacturers.
