Hex Bolt Wholesaler introduces 3 common materials of hexagon head bolts:
1. The material of the inner and outer hexagon head bolts is generally 304 stainless steel, and a layer of anti-oxidation is formed on the surface. This material is added with molybdenum, which has good corrosion resistance, wear-resistance, and rust resistance, and can be strong Up to 4.8, it is often used for general cold processing and drawing, and the corrosion resistance can be well used in the production of seawater and some chemical media. According to the diameter of the bolt head, it can be divided into M4, Hexagon head bolts of different specifications such as M5, M6, and M8. The standard outer hexagonal human ten sub-slot design, the round stainless steel material can play a good anti-corrosion effect even when used in damp water, the standard smooth section, exquisite craftsmanship, and no residual burrs on the surface. In the process of fixed rotation, it is not easy to slip, and the deep design of the thread is more evenly stressed during use, and the screw teeth are sharper, so as to achieve a firm effect.
2. The galvanized carbon steel material, the strength can reach 8.8, has good tensile strength and hardness; there are also nylon hexagon head bolts made of high-quality nylon raw materials because nylon has good insulation and no magnetism. With good heat insulation and corrosion resistance, it is widely used in electronic communication equipment, medical equipment, and green energy equipment. Non-magnetic can be well protected from the interference of electronic information, and good insulation and flame retardancy are used in power engineering to ensure safety, so some special materials are used because of their unique material Industry.
3. The hexagonal head bolts made of brass also have good rust resistance, corrosion resistance, and oxidation resistance; the hexagonal bolts made of alloy steel have precise hexagonal holes so that the service life is longer, and it is also knurled It is easy to operate, the full thread can increase the closeness with the workpiece during the rotation process, and improve the fatigue strength of the screw. The metal material of alloy steel makes the bearing area of the bolt head wider and the screw bears a greater tensile load. The design of the outer circle joint of the bolt head effectively reduces the fatigue strength, so that it can be smoothly transitioned during fixing. It must be effectively anti-rust, anti-loose, and anti-crack, and it is very safe and simple to use.
