4. Lock washers: capable of locking the nut to prevent it from loosening during threaded connections.
The standard specification of large flat washers
Large flat washers have strict standard specifications, including inner diameter, outer diameter, thickness, material, hardness, and other aspects. The development of these specifications can ensure that the large flat washers in use have stable performance and reliable quality to avoid equipment damage and personal safety accidents caused by errors.
Commonly used extensive flat washer standards are:
1. International standard ISO7092/7093: respectively, the shape and size of the large flat washers; respectively, the standard size of the different types of large flat washers, and for various types of washers to make other material selection recommendations;
2. Standard ANSI/ASMEB18.22. European standard DIN125/DIN9021 provides geometric parameters and allowable error ranges for large flat washers.
Large flat washers industrial application solutions
1. In the manufacturing process of automobiles, motorcycles, bicycles, and other means of transportation;
2. In the manufacturing process of various means of transportation such as ships, airplanes, etc.;
3. In manufacturing hardware facilities in construction, machinery, electric power, and other industries.
