Product description

This Tr 20 X 4 Screw Assembly is a high-precision trapezoidal lead screw used in the positioning systems of Snap-On tire changers and wheel balancers. The 20mm diameter and 4mm pitch design provide the mechanical advantage and accuracy needed for fine adjustments of the tool head or wheel spindle. Worn threads or a bent screw can cause binding, inconsistent movement, or positioning errors that affect the quality of the tire service. This assembly includes the necessary mounting hardware to restore smooth, linear travel to the machine's moving components. It is manufactured from high-strength alloy steel to resist wear and maintain its accuracy through thousands of service cycles.
