Hexagon head bolt is the screw that we often use in our daily life. The hexagon head bolt is only one of them. The bolt is used to fix some mechanical equipment. What kind of material is used to ensure the stability of the equipment in the process of application?

Hexagon head bolt, taken out of context, means that the head of the bolt is a fastener with hexagonal external thread. We need to use a wrench to roll the hexagon head bolt. The English name of hexagon head bolt is hex bolt. According to the national standard of ASME b18.2.1, the head height rod length of hexagon head bolt are larger than that of hexagon head screw. Therefore, the hexagon head screw prepared in accordance with ASME b18.2.1 standard can be used in any one hexagon head bolt.

304 stainless steel is generally used as the material of internal external hexagon head bolts, a layer of antioxidant will be formed on the surface. This material with molybdenum has good corrosion resistance, wear resistance rust resistance. The strength can reach 4.8 grade. It is often used for general cold working drawing, the corrosion resistance can be well applied to seawater some chemical medium production, According to the diameter of the bolt head, it can be divided into M4, M5, M6, M8 other external hexagon head bolts. According to the standard plan of external hexagon groove, the smooth stainless steel material on the surface can play a good anti-corrosion effect even if it is used in wet water. The standard smooth cross-section, exquisite technology, no residual burr on the surface, it is easy to slip in the fixed rotation process. The deep planning of screw thread is more uniform in the application process, the screw teeth are more sharp, then reach the robust role
