Designed to be used with an impact wrench (within its listed torque), this extender combines a flat head profile for access with versatile drive options. It comes with 1/4-inch, 3/8-inch, and 1/2-inch square drive adapters, plus a 1/4-inch bit drive adapter—so you can match common sockets and bits without swapping tools mid-task.
Made from high carbon steel and measuring 13.4 inches long and about 0.63 inches thick, it’s a practical add-on for automotive repairs, furniture assembly, and general mechanical work where reach and clearance matter.
