The rear axle nut wrench is made of very tough 3/8 inch thick stainless steel, has long arms for twisting with both hands. A 1/2 inch square hole was included for use with a long breaker bar and the arms were sized to fit inside 1 1/4 inch PVC pipe so that a long handle can be placed on both sides. This tool works well and performs a difficult task. It is one more special tool that belongs in the active mechanic's tool box.
