Lock Plate
Mack

This component provides a secure, stable mounting surface that helps prevent rotation and loosening of critical assemblies. Carefully engineered to withstand vibration and harsh operating conditions typical of heavy duty trucks, the lock plate distributes load across fasteners and aligns mating parts with precision. Its design supports reliable clamping force, maintaining structural integrity in suspension, steering, or drivetrain linkages where misalignment can lead to wear or failure. When used in conjunction with corresponding bolts and washers, this plate acts as a restraint, reducing the chance of bolt creep under dynamic loads and helping to preserve seal life and gasket performance in adjacent interfaces. Materials and finish are selected to resist corrosion in exposed environments, extending service intervals and lowering maintenance costs. Proper installation torque and seating are important to realize the full benefit of the plate, which contributes to predictable diagnostics and safer operation. Source One Parts Center
