  1. Fasteners produced by China Stud Supplier are the most widely used mechanical basic parts. As my country joined the WTO in 2001 and entered the ranks of major international trade countries. my country's fastener products are exported to countries all over the world, and fastener products from all over the world are constantly pouring into the Chinese market. Fasteners, as one of the products with a large import and export volume in China, are in line with international standards. They have important practical significance for promoting Chinese fastener enterprises to the world and promoting fastener enterprises to fully participate in international cooperation and competition. Strategic significance. Because the specifications, dimensions, tolerances, weight, performance, surface conditions, marking methods, and acceptance inspection, marking and packaging of each specific fastener product are specified in several national (industry) standards , For example, English, German and American. Locking of fasteners generally occurs on products made of stainless steel or alloy materials. Weigao Industrial Bolt Factory will give a detailed introduction in this regard. This is because these metal materials themselves have the ability to prevent corrosion.Once the metal surface of the fastener is damaged, an oxide layer will appear to provide protection and prevent the corrosion from increasing, but when the fastener is locked, the application The pressure and heat generated by the force will destroy the oxide layer, causing blockage or shearing between the metal threads, and then the phenomenon of adhesion, which is locked. Under normal circumstances, aluminum has sufficient corrosion resistance. And when the expected exposure environment is very harsh, its corrosion resistance can be greatly improved by anodizing. Anodizing is an electrical machining process that forms an oxide film on the metal surface. Anodizing not only enhances the ability to resist corrosion, but also enhances the protection against wear and scratches. The anode coating has many colors for decoration and identification purposes. In atmospheric corrosion, aluminum forms a light gray oxide film on the surface. These corrosion products do not contaminate the aluminum surface or spread to adjacent surfaces. It behaves differently from many other metals under corrosion.
