Tie rod wrenches come in a variety of sizes and designs. The tie rod wrench pictured here is used for adjusting tie rods on vehicles with rack and pinion steering and works on most spline, hex, and two flat design tie rods.

This is an adjustable tie rod wrench which works with nine different sizes. The tool's spring-loaded upper jaw pivots to accommodate tie rods ranging in size from 10mm-18mm and is self adjusting.

Cam action increases the gripping pressure as the load applied to the handle increases.
