Customized Hexagonal Locking Nuts for Steam Turbines with Heat-Resistant High-Strength Materials and Precision Machining

Hexagonal nuts are specialized locking nuts engineered specifically for high-temperature applications within steam turbines. Our company offers comprehensive customization and reverse engineering services, ensuring precision machining that strictly adheres to technical specifications and drawings.

These precision-engineered nuts feature threads with full, regular profiles and accurate fitting clearances, providing perfect compatibility with high-temperature studs and bolts of corresponding specifications.

• Enhanced resistance to thread stripping and chipping
• Minimal preload attenuation under high temperatures
• Flat end faces for uniform pressure distribution
• Tight and stable fitting after locking
• Long-term reliability in severe operating conditions

Designed to withstand the extreme conditions of steam turbine operation—including high temperature, high pressure, and thermal cycling—these nuts ensure reliable fastening in high-temperature zones. They effectively eliminate risks associated with flange loosening and medium leakage, serving as core spare parts for routine maintenance of high-temperature sections in both steam turbine and gas turbine units.
