Service HotlineFor a long time, the rivets used in general riveting, especially the ordinary rivets and bolts and other fasteners commonly used in steel structures such as vehicles and bridges, have low connection reliability, especially under alternating load and impact conditions. Looseness is easy to occur, the maintenance cycle is short, and the maintenance cost is high in the later period, which cannot meet the requirements of railway freight.
nut is a connecting nut, a part that is screwed together with a bolt or Galwayconnecting screw for fastening, and a component that must be used in all production and manufacturing machinery. There are many kinds of nuts, we commonly have standard, German standard, British standard, American standard, Japanese standard nuts. According to different materials, nuts are divided into carbon steel, high strength, stainless steel, plastic steel and other types. According to the product attributes, the corresponding standard numbers are divided into ordinary, non-standard, standard, new standard, American system, British system, and German standard. Different sizes, unequal threads are divided into different specifications. The general standard and German standard are represented by M, and the American system and the British system are represented by fractions or #. The specification nut is a part that tightly connects the mechanical equipment. Only through the inner thread, the same specification nut and screw can be connected together. The anti-loosening of the screw has always been the intersection of people's attention. The anti-loosening of the nut is of great significance to the current life, because it directly affects the service life of the machine. Therefore, it is also very important for people's life safety. Technicians can achieve the anti-feeding of the nut by changing the material of the nut and increasing the method of tightening the nut, but these methods cannot fundamentally solve the problem, and increase the tightening nut while taking up more space.
To sum up, the chip nut provided by Guangdong Yueluo Hardware Industry Co., Ltd. has a circle of serrated teeth 1011 protruding outwardly on the edge of the welding end face 101. During welding, the excess solder overflows and flows to the periphery. In the gap between the serrated teeth 1011, on the one hand, the solder on the welding end face 101 can be made uniform, so as to ensure that the welded chip nut is neat and beautiful; The welding area is increased, and the firmness and reliability of the welding are improved.
All kinds of industrial equipment need to be installed on the equipment foundation for work and operation. The equipment foundation includes concrete foundation, steel base, steel platform, steel frame and other forms.
The quality of the GalwayGalwayGalwaycombination screw should start with the screw wire of the GalwayGalwayGalwaycombination screw manufacturer. The wire of the screw is the first hurdle to determine the quality of the GalwayGalwayGalwaycombination screw. Even if the wire is not good, even if the production equipment is advanced and the staff is skilled, it is impossible to produce high-quality GalwayGalwayGalwaycombination screws. In the second look at the quality of the GalwayGalwayGalwaycombination screw products, from the overall aesthetics of the GalwayGalwayGalwaycombination screw. A combined screw is formed, the size of the screw head, the superior appearance of the flat washer, whether the screw thread can pass the stop gauge, etc. These are all things that need to be detected. A good GalwayGalwayGalwaycombination screw, its overall standard can meet the national standard requirements, or customer requirements. Finally, the quality of the GalwayGalwayGalwaycombination screw product is seen from the color of the plating. Of course, the iron GalwayGalwayGalwaycombination screw needs to be plated, but the stainless steel GalwayGalwayGalwaycombination screw does not need it. Some of them are passivation at most, in order to increase the salt spray resistance of stainless steel GalwayGalwayGalwaycombination screws. In the electroplating color of the GalwayGalwayGalwaycombination screw, some of them are not well controlled, which will produce a great color difference. That doesn't look good.
