Long impact socket for use with electric or pneumatic impact wrenches with a 12.5 mm (1/2") drive. Ideal for deep-seated screws and protruding threaded rods. The impact technology ensures above-average durability, even under extreme conditions. Equipped with the "Take it easy" tool finder with color coding by size for easy and quick identification of the required tool. Features a hexagonal profile and a groove with a hole. The hexagonal profile allows for the transfer of high forces and puts less stress on the edges of the screw nut or bolt head compared to a twelve-point profile.
