Long ¼" hand and machine socket (ISO 2725-Part 3) with ball retention groove; for external hex screws and nuts. Suitable for use in hand and machine operations (non-impact), even with deep-seated screws 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 transmission of high forces and puts 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 even in confined spaces due to their small return angle.
