• material: premium flex chrome vanadium steel

• entirely hardened and tempered

• for one-way ratchet 190.9/2BI

• made according to standard ISO 3315

• Simple use

  The operation of the ratchet accommodating the sockets is based on a 75-tooth mechanism, which divides the 360° full circle into sections of 4.8-degree angles and thus guarantees simpler use even at nearly inaccessible points. With larger ratchet increments, fewer turns and less effort, you can achieve greater reliability and higher precision.

• Accuracy

  Together with the indispensable ratchets, Unior sockets allow even, predictable and precision tightening and loosening of screws and nuts -working with Unior ratchets is safer and more accurate.

• Safety

  Special socket retention system with a one-touch release button ensures greater safety at work and an increased socket locking speed.
