Upgrade & Restore Your Tire Changer's Mechanical Rigidity

The 1"/2"-13" 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 dangerous play in foot pedals and table assemblies. This fine-thread replacement nut holds torque securely to prevent joint loosening.

Machine Location:

This fastener threads directly onto the foot pedal linkages, cylinder mounting pins, or vertical slide locking shafts inside the tire changer's cabinet.

• Carbon Steel Forging: High-tensile carbon steel body built to resist thread stripping and mechanical shear.
