Questions & Answers

  • I wanted to loosen the wheels on the car using a ratchet, and now it isn't working. Perhaps the mechanism broke down? Did I use the right ratchet?
    The ratchet article 190.1/1LG is intended for unscrewing car wheel bolts. Other ratchets in Unior's range are not designed to unscrew car wheel bolts.
  • 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.
