Product Description

 

1. Prevent Vibration Loosening with Our Hydraulic Lock Nut

This is our hydraulic lock nut, designed for equipment that experiences strong vibration and dynamic loads. Ordinary nuts tend to loosen gradually under such conditions, which can lead to equipment failure and downtime.

Our hydraulic lock nut is engineered to resist vibration loosening. It maintains its locking position even under continuous operation, helping your equipment run longer with fewer interruptions, reduced maintenance, and lower repair costs.

2. High Hardness and Precise 6H Thread Fit

We manufacture the threads to a 6H tolerance, ensuring a precise and smooth fit between the nut and the bolt. This reduces sticking and prevents unwanted movement during operation.

The hardness is controlled at HRC 28–38, higher than standard nuts, which improves wear resistance and extends service life.

The locking torque ranges from 5 N·m to 200 N·m, depending on the size and application. Smaller sizes require lower torque, while larger sizes require higher torque. We can customize the torque according to your specific requirements.
