This 6 point ,3-3/4" socket has a 3/4" square drive opening, permitting the use of an extension and torque wrench to tighten the locknut as required.
Socket is made of high-strength steel so the openings resist rounding out.
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.
NOTE: Sockets are designed for use with 3/4" square-drive manual tools only. Impact tool use voids sockets warranty.
