Lock Plate for Grooved Nut
It fits precisely into the grooves of the axle nut and locks securely against the hub or washer, ensuring the nut maintains proper bearing preload under heavy loads and continuous vibration. Manufactured from high-strength steel, the plate resists bending, wear, and deformation, providing long-lasting retention. Its simple yet durable design adds a critical layer of safety to the axle system, protecting the hub and bearings from failure caused by nut movement.
By securing the grooved nut in place, the lock plate enhances vehicle reliability, reduces maintenance frequency, and ensures safe axle performance during demanding on-road and off-road conditions.
Key Features
- Robust lock plate designed for grooved axle nuts
- Prevents nut loosening under vibration and heavy torque
- High-strength steel construction for durability
- Ensures stable bearing preload and hub alignment
- Essential for safe and reliable rear axle performance
