GB/T 933-1988 specifies the dimensions, materials, and performance requirements for self-locking nuts with two lugs, anchor features, and sealing capability. These nuts are used in aerospace and mechanical systems where vibration resistance and airtight sealing are critical, such as in aircraft engine mounts, fuel system connections, or pressurized compartments. The standard ensures reliable fastening under dynamic loads and prevents fluid or gas leakage in high-integrity assemblies.
