Long ¼" hand and machine socket (ISO 2725-Part 3) with ball detent groove, suitable for external hex screws and nuts. Ideal for use in hand and machine operations (non-impact), even for deep-seated fasteners and protruding threaded rods. Equipped with the Take it easy tool finder, which provides color coding by size for easy and quick identification of the required tool. Grippy, even with oily hands. With hexagonal profile, allowing for the transmission of high forces and putting less stress on the edges of the screw nut or screw head compared to a twelve-point profile. Fine-toothed ratchets make the use of a twelve-point profile unnecessary in tight spaces, thanks to their small return angle.
