Application Summary AI generated

GB/T 1181-1998 specifies the design and dimensional requirements for interference-fit threads used in mechanical assemblies where a tight, press-fit connection is needed to prevent loosening under vibration or load. It is applied in industries such as automotive, aerospace, and heavy machinery for components like studs, bolts, and threaded inserts that require high torque retention and sealing. The standard ensures consistent thread geometry and interference levels for reliable performance in static and dynamic mechanical systems.
