Long ¼" hand and machine socket (ISO 2725-Part 3) with ball catch groove; for external hexagon screws and nuts. Suitable for use in hand and machine operations (non-impact), even for deep-seated 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. With hexagonal profile. The hexagonal profile allows for the transfer of high forces and places less stress on the edges of the screw nut or screw head than a twelve-point profile. Additionally, fine-toothed ratchets make the use of a twelve-point profile unnecessary even in confined spaces due to their small return angle.
