Service Hotline1. Ordinary outer hexagon - widely used, characterized by relatively large tightening force, the disadvantage is that there must be enough operating space during installation, and adjustable wrench, open-end wrench or glasses wrench can be used during installation, all of the above wrenches require a large amount of space. operating space. 2. Cylindrical head hexagon socket - is the most widely used of all screws, because it has a relatively large tightening force, and can be operated with a hexagon wrench. It is very convenient to install and is used in almost all kinds of structures. The appearance is more beautiful and neat. The disadvantage is that the tightening force is slightly lower than the outer hexagon, and the inner hexagon is easily damaged due to repeated use and cannot be disassembled. 3. Pan head inner hexagon - rarely used mechanically, the mechanical properties are the same as above, mostly used in furniture, the main function is to increase the contact surface with wooden materials and increase the ornamental appearance. 4. Headless inner hexagon - must be used in certain structures, such as the top wire structure that requires a large top-tight force, or where the cylindrical head needs to be hidden. 5. Countersunk head hexagon - mostly used in power machinery, the main function is the same as the inner hexagon. 6. Nylon lock nut - a nylon rubber ring is embedded in the hexagonal surface to prevent the thread from loosening, and it is used on strong power machinery. 7. Flange nuts - mainly play the role of increasing the contact surface with the workpiece, mostly used in pipes, fasteners, some stamping parts and casting parts. 8. Ordinary hex nut - the most widely used and one of the most common fasteners.

At present, in the standard cabinets of computers, networks, automation, etc., to fix the equipment in the cabinet, it needs to be fixed by using fasteners. The nuts in the existing fasteners are ordinary nuts, which are internal card structures. , there are the following shortcomings: 1. The installation and disassembly are complicated, and a large amount of force is required to insert the nut during installation and disassembly, and the nut cannot be installed and disassembled at all due to the processing error of each nut; 2. After the nut is used for a long time, the nut The card edge will have slack problem, which will affect the use; 3. Installation or disassembly is easy to cause problems such as falling, which may cause electrical short circuit, etc., and there are potential safety hazards; 4. The efficiency of equipment installation is low.
