Hwashin Bolt Industry manufactures and supplies high-strength, high-precision compressor rotor bolts used to secure high-speed rotors in centrifugal and screw compressors, supporting stable operations across plants, shipbuilding, and power generation industries.
Compressor Rotor Bolt Technology
Using API 20E high-strength alloy steels such as ASTM A193 B7 with specialized heat treatment, these bolts are optimized for anti-loosening performance and fatigue strength under extreme rotational speeds. Precision machining within ±0.1 mm tolerance, specialized thread geometry for uniform torque distribution and preload management, and custom production based on rotor dimensions—including length, diameter, and UN thread specifications—are available. Compressor rotor bolts are critical safety components during overhauls and new installations, ensuring long-term stable operation.
