ASME B18.21.1 is a standard developed by the American Society of Mechanical Engineers to standardize the dimensional, material, and performance requirements for external toothlock washers. External tooth lock washers are widely used washers in threaded connections, through their special design and materials, can provide additional tightening force and anti-loosening ability to ensure the reliability and safety of threaded connections.
The main function of external toothlock washers is to increase the tightening force and anti-loosening capacity of threaded connections. In threaded connections, threads tend to loosen automatically due to vibration, shock, or temperature changes, which can lead to loosening and failure of the connection, which may have a negative impact on the normal operation of work machines and equipment. External tooth lock washers, with their special external tooth design, can be tightly fitted to threaded pins or nuts to provide additional tightening force in threaded connections. When the threaded connection is subjected to external forces, the external tooth lock washer can, through its special shape and elastic deformation, increase the biting force of the threaded connection, effectively preventing the loosening of the threads.
