Hexagonal head bolts are also often used in our daily life screws, hexagonal head bolts are just one of the bolts are used to fix some mechanical equipment and the use of reinforcement parts, hexagonal head bolts used what kind of material to ensure that the use of the process to maintain the stability of the equipment between it?
?Hexagonal head bolts are hexagonal, or hexagonal or hexagonal, and therefore called "internal and external hexagonal head bolts".
?Internal and external hexagonal head bolts are generally made of 304 stainless steel, the surface will generate a layer of antioxidants, this material added molybdenum, has a very good corrosion resistance, and wear-resistant and rust-resistant, the strength can reach 4.8, often used in general cold processing and stretching pumping, corrosion resistance can be very well used in seawater and some of the chemical medium of the production of inside, according to the bolt head diameter size can be divided into M4, M4, M4, M4, M4, M4, M4, M4, M4, M4 and M4. According to the size of the diameter of the head of the bolt can be divided into M4, M5, M6, M8 and other different specifications of the hexagonal head bolts. Standard external hexagonal human ten sub-groove design, the surface of the rounded stainless steel even when used in the wet water can play a good role in corrosion prevention, standard smooth cross-section, exquisite craftsmanship, the surface of the residual burrs, in the process of fixing the rotary process is not easy to slip, and the threads of the deep design in the use of the process of the force is more uniform, the screw teeth are sharper, so as to achieve the role of solid.
?In addition to the use of stainless steel material, there are some carbon steel zinc-plated material, the strength can reach 8.8 level, has good tensile strength and hardness; there is also the use of high-quality nylon raw materials made of nylon hexagonal head bolts, because the nylon has a very good insulating properties, non-magnetic and heat insulation and good, but also corrosion resistance and many other characteristics, is widely used in electronic communication equipment, medical equipment, green energy equipment, medical equipment, green energy equipment, etc. Non-magnetic can be very good from the electronic information of the dry guide, and insulation, flame retardant good is used in electric power engineering to ensure the safety, so because of its unique material and is used in some special industries.
Hexagonal head bolts made of brass also have good rust resistance, corrosion resistance and oxidation resistance; alloy steel hexagonal bolts with precise hexagonal points, thus a longer service life, but also for the convenience of knurling operation, full threads can be in the process of rotating to increase the degree of closeness with the workpiece to improve the fatigue strength of the screw, alloy steel metal material makes the head of the bolt a wider bearing area, the head of the bolt, the head of the bolt, the head of the alloy steel material makes the head of the bolt a wider bearing area, the head of the alloy steel material makes the head of the bolt a wider bearing area. The bearing area of the head of the bolt is wider, and the tensile load of the screw is bigger, and the bolt? The head of the outer circle of the combination of the design effectively reduces the fatigue strength, so that when fixed to a smooth transition, to effectively prevent rust, anti-loosening, anti-cracking, the use of a very safe and easy.
