  • Metal locking nuts have superior temperature resistance and durability compared to nylon locking nuts. They are suitable for harsh working conditions such as high temperatures, high vibrations, and strong corrosion.

    For example, they are used for fixing components in boilers, ovens, and heat treatment furnaces; for long-term fixation of parts in wind turbines, towers, and bridges; for track fasteners and chassis fixation in high-speed trains and subways; and for fastening high-temperature and high-vibration components such as exhaust pipes, turbochargers, and chassis suspensions.
