Crowfoot Wrench Set. Sizes range from 10mm - 22mm and 7/8" - 3/8.
A crowfoot wrench, also known as a tight clearance offset socket or crowfoot socket wrench, is an open-ended wrench with a short handle and a head that resembles a crow's foot. It's used to tighten or loosen fasteners in hard-to-reach places, such as in tight spaces, from the top, or on the side. Crowfoot wrenches can also provide more torque than a regular wrench.
