What is the tolerance range of precision screws?
The main purpose of the screw is to make the industrial product form a fixed one. In use, it often happens that the teeth cannot be closely attached, the screw head will be broken if the screw is locked too hard, or the tooth pattern is not properly locked, etc., and the use conditions are not met, all of which are quality. the problem of accuracy. Screws are mass products, not handmade works of art. In mass production, the purpose is to achieve high-precision and stable quality and popular prices to supply consumers. The accuracy of screws is usually 6g, and the rough screws used in construction projects are 14g. The value of screws is very important. In the world, there are examples of automobile factories going bankrupt because of poor screw quality; there are also examples of planes falling and vehicles being overturned because of poor screw quality.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (10), which can effectively prevent the problem of poor memory contact caused by the increase of the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixation, and can effectively control the deformation. effect.
In response to the above situation, Yueluo uses various methods to fasten the locked nuts and bolts in actual operation, such as super glue, electric welding, secondary reinforcement by perforation, etc., but there is still no way to get it right Solve the phenomenon that the nut is loose and displaced.
The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above-mentioned shortcomings of the prior art, and provide a hidden screw fastener, which avoids the defect that the screw end cap is directly exposed when the traditional screw is tightened, which affects the appearance. Washers and shields hide the end caps of the screws, which are both beautiful and insulating, preventing the screws from rusting, and avoiding scratches due to burrs on the ends of the screws, which are not only beautiful but also practical and safe.
