Powerbuilt 2 Piece Spring-Loaded Crowfoot Wrench Set

This set can do the work of multiple wrenches, so you’ll save time and toolbox space using these innovative spring-loaded auto-adjusting crowfoot wrenches. They automatically open to the correct size to grab and turn nuts, bolts, tie rods, pipes, and other fittings of various sizes. And the jaws ratchet back between turns, eliminating the need to remove and replace the wrench as you tighten or loosen. The jaws serrated teeth ensure a firm and secure grip. Wrenches have both male and female square drive attachments in 3/8 inch or1/2 inch; simply attach the wrench to a breaker bar, ratchet, or use the built-in square drive to attach an extension bar for use as a handle and get to work. The combination of both wrenches gives users a wide and usable range eliminating the need for additional wrenches; the 3/8 inch drive wrench jaw range is 5/16 inch to 11/16 inch, and the 1/2 inch drive wrench jaw range is 9/16 inch to 1 1/4 inch. Made of chrome vanadium steel, this set will last a lifetime.
