Upgrade & Restore Your Tire Changer's Mechanical Rigidity

The Whiz Lock Nut is a heavy-duty, direct-replacement locknut/jam nut designed to secure critical pivot pins, cylinder rods, and mechanical linkages on professional tire changers.

Under continuous mechanical shock and intense shop vibrations, locking nuts can back off or strip, introducing play in foot pedals and table assemblies. This fine-thread replacement nut holds torque securely.
