Upgrade & Restore Your Wheel Balancer's Shaft Rigidity

The 13" Hex Nut, 1"/2" is a high-tensile, direct-replacement locknut/jam nut designed to secure the heavy-duty threaded shafts, pulleys, motor mounts, and piezo sensor assemblies of professional wheel balancers.

Under continuous mechanical vibration and high-speed motor rotation, structural nuts can stretch, cross-thread, or back off. Replacing worn locking hardware ensures perfect axial clamping torque and protects key shafts from rotational drift.

Machine Location:

This nut installs directly on the main threaded shaft, pulley mount, motor assembly, or sensor bracket assemblies of the wheel balancer.

Key Features & Specifications

• Concentric Thread Lock: Machined from heavy-duty forged steel to distribute torque evenly and prevent high-speed rotational slip.
• Moisture & Dust Defense: Finished with a zinc-plated or black-oxide coating to repel shop moisture, grease, and tyre lubes.
• Extreme Duty Holding: Built to maintain precise structural torque to prevent balance sensors from losing calibration.
