Socket has a 3/4" square drive opening, permitting the use of an extension and torque wrench to tighten locknut as required. Locknut removal and installation is simple, even when wide-rim wheels are involved, since a long extension may be attached to the socket to provide the necessary clearance. Socket is made of high-strength steel; openings resists round-out. Warranty void if tool is subjected to impact wrench use.
