We can't ignore the processing of non-standard screws, because it makes the whole world solid. We often see that because of the existence of two non-standard screws on a box, it is difficult for you to open it completely. If the screw is removed. The figure of the non-standard screw is also the figure of a person. Although it is small, if it is placed in the correct position, the power it exerts cannot be underestimated. The machine also has life because of the connection of various non-standard screws. If there are no non-standard screws, it is just a pile of copper and iron.

Non-standard screw processing is not a simple task. The non-standard screw thread on the non-standard screw should be manufactured according to the rules. This rule is the standard standard. In its industry, the most commonly used standard in the world is GB China. There are also many categories of national standards, including organic screws, self-tapping screws, wallboard screws, fiberboard screws, drill-tail screws, wood screws, hexagonal wood screws, non-prolapse screws, and combination screws. Its use is different, its head and body are different, and its head shape can be divided into: hexagonal head, hexagonal head flange, square head, T-shaped head, oblate head, cylindrical head, round head Yes, pan-headed, countersunk, semi-sunk.

The manufacturing process of its processing is also different. Even if the development and research of non-standard screws are in progress, a good non-standard screw can be developed and obtained a special patent from the bank, which will have a high economic value. We must know that the processing of non-standard screws is not only the manufacture of a small tool, but also contains very strong scientific and technological forces. We must treat non-standard screws with a serious and responsible heart, so as to make the world safer and more stable.
