Description:
Materials - These thread-cutting nuts with an external tooth washer are made of zinc plated steel material, with fine workmanship, beautiful appearance, good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties, and are sturdy and durable.
Design - The locking nut includes a hexagonal nut with a pre-assembled, freely rotating outer toothed locking washer. The nut connection has an external star-shaped washer that, when tightened, bites into the elastic surface, providing a locking effect. Its thread-cutting feature ensures proper fitting over bolts, ensuring secure fastening, and is not easy to slip.
