Zibo Qiangda Group Co., Ltd. focuses on the needs of the wind power industry and launches high-performance and high-strength nuts designed specifically for wind turbines. With its excellent fatigue resistance and precise preload control, this product effectively solves the problem of nut loosening and failure during long-term operation of wind power equipment.

The high-strength nut is made of 42CrMo high-strength alloy steel. After special quenching and tempering, the uniformity of the nut hardness is controlled within a very small tolerance range to ensure a close fit with the bolt. The innovatively designed anti-loosening structure greatly improves the anti-loosening performance of the nut through a unique combination of thread tooth profile and anti-loosening washers. In fatigue tests simulating the actual operating conditions of wind power equipment, the nut can withstand more than 1 million alternating loads without loosening or failure.

At present, this high-performance and high-strength nut has passed a number of authoritative certifications and has been successfully applied to a number of large-scale wind power projects. A relevant person in charge of Zibo Qiangda Group revealed that the group will continue to optimize product performance and contribute "powerful strength" to the development of the global wind power industry.
