Fasteners can be said to be the most widely used mechanical parts! Its figure is everywhere. You can see all kinds of fasteners on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, chemicals, meters and supplies. The 13 most commonly used fastener parts: bolts, studs, screws, nuts, self-tapping screws, wood screws, washers, fixing rings, pins, rivets, components, connection pairs, wire thread inserts!
Fasteners are the most versatile basic components with large volume and large area. They are closely connected with the steel industry at all levels. Fasteners can be made of steel, non-ferrous metals, stainless steel, titanium alloys or other engineering materials. The processing method can be hot processing or cutting, but more than 90% of the processing is performed by cold pressing. The products manufactured by this method have high precision, high quality and high production efficiency. China's fastener industry has maintained two positions for five consecutive years. The number has grown steadily.
Even if the cold head steel used for cold head processing fasteners meets qualified wire rods within the scope of the standard requirements, more specific requirements are required for the characteristics of the fastener industry, and steel mills need to work closely with downstream users. The improvement of the production level of Chinese fastener enterprises is inseparable from the improvement of fastener materials. The development of new cold head materials is also inseparable from the fastener company. The development of the fastener industry is inseparable from the support of the steel industry. As long as the two have established a good cold head processing cooperation relationship, both the fastener industry and the steel industry will achieve better development.
How to regulate the fastener industry
High-strength fasteners indicate that there are many fastener manufacturers. This has led to fierce competition in the entire fastener industry. After fierce competition, many unethical manufacturers will use some very extreme methods to differentiate themselves from the fierce competition. Therefore, it is easy to plunge the entire fastener industry into chaos. So how should the fastener industry be regulated?
First of all, industry regulations should be released as soon as possible. Good industry regulations can play a good role in regulating every manufacturer in the industry. This is the code of conduct for all manufacturers and can be avoided first. The unfair competition behavior of various manufacturers has promoted the healthy development of the entire fastener industry.
Second, product quality standards should also establish product quality standards. This is not only conducive to the development of the entire industry, but also conducive to the protection of consumption, is also very beneficial to the legitimate rights and interests of investors.
There are many kinds of electroplating of iron combination screws: ordinary and environmentally friendly. For example: color zinc, generally called red color. White zinc, black zinc, white nickel. Blue zinc. There are environmentally friendly color zinc, environmentally friendly white zinc, and environmentally friendly blue zinc. Environmentally friendly white nickel. There are more advanced ones. Nickel on copper, nickel in brine. Tools/Materials Screw wires, iron screw wires include 1010, 1018, 10B21, etc. Stainless steel screw wires include SUS201, SUS304, etc. Steps/Methods The requirements for the material of the combined screw depend on which material is required, whether it is iron or stainless steel. What is the national standard number of the combination screw? There are GB9074.8 and GB9074.4. There are GB9074.13 and so on. The mechanical performance and strength requirements of the combined screw need not be hardened. The level requirements are divided into 4.8 and 8.8 l...
