Long ½" hand and machine socket (ISO 2725-Part 3) with ball retention groove; for external hexagon screws and nuts. Suitable for use in hand and machine operations (non-impact), even with recessed fasteners and protruding threaded rods. Features the Take it easy tool finder with color coding by size for easy and quick identification of the required tool. Textured for easy gripping, even with oily hands. The hexagonal profile allows for the transmission of high forces and places less stress on the edges of the nut or screw head compared to a twelve-point profile. Additionally, fine-toothed ratchets make the use of a twelve-point profile unnecessary in tight spaces due to their small return angle.
