For nuts and bolts, the 20V MAX Lithium-Ion 1/2″ Impact Wrench (Tool Only) offers a secure detent pin fitting that can be relied upon to hold, even when used over your head, as mechanics may need to. Made for professionals and hobbyists alike, for auto repairs and other do-it-yourself jobs, the cordless impact wrench makes it easier to drive and remove fasteners from a variety of materials, whether wood, metal or concrete. The lightweight and compact design means that even the tightest spots are reachable, and at a weight of 3.4 pounds, it is easy to hold all day without feeling too . At only 5.7-inches long, the size will not impede progress in small spaces, and the 1/2″ impact wrench fits comfortably in your hand. The max torque is 150 foot-pounds, and it can reach 2,700 impact per minute, giving you the power to finish the job properly. Three bright LED lights, with a 20-second delay after trigger use, help keep shadows away from the impact wrench tool and let you see clearly as you work.
