Upgrade & Restore Your Tire Changer's Pivot Assemblies

The 5/8" Lock Washer is a heavy-duty mechanical washer engineered to distribute clamping loads evenly and reduce surface friction on moving pivot points and structural joints of professional tire changers.

Regular maintenance and timely replacement of worn or scored washers are critical to preventing mechanical binding on main hinge pins and keeping assemblies pivoting smoothly.
