Security Locknut has been a trusted railroad supplier for more than 50 years. Using Security Locknuts will increase the interval of time between inspections and reduce your maintenance costs. With no special tooling required, your maintenance team will be able to quickly and easily remove and reinstall the nut, saving both time and material cost.

One of the key features of Security Locknuts is their prevailing torque design. This unique attribute ensures that the locknut maintains a consistent level of resistance to rotation, even in the face of external vibrations, shocks, or other dynamic forces. This characteristic helps prevent self-loosening over time, reducing the risk of equipment failure and enhancing the overall safety of the connected components.
