Long Screws Factory, Shenzhen Shi Shi Tong

Long screws, as the name implies, are even longer than ordinary screws.

What are the materials of the long screws? There are mainly three materials: stainless steel, carbon steel and aluminum, among which there are relatively more stainless steel. This is because long screws made of stainless steel usually only need to be cleaned to remove oil, and can be delivered after checking quality and quantity. However, long screw made of carbon steel usually require surface treatment. Without surface treatment, it is easy to rust. The longer the length of the screw, the more expensive the electroplating, generally more than 300mm of the screw very few electroplating plants can be. Due to the aluminum material itself, the longer the screw, the more difficult to shape, can only do not so long screw.
