Industry knowledge：

With the development of the times and the progress of the mechanical age, all walks of life also have higher requirements for screw fasteners. At present, the domestic screw fasteners have been oversupplied, while the high-end screw fasteners, such as high temperature resistance, corrosion resistance, high strength, non-standard special-shaped, Special performance fasteners are in short supply, some still need to rely on imports. The State Bureau of machinery has listed “common standard fasteners” as a restricted product“ And “high strength special-shaped screw fastener” is listed as the current product to encourage development. Pingood screw fasteners are also improving their own production technology level with the improvement of national industrialization level and technological progress. Improve product quality.
