On one side, it is connected to chestnuts or handles with a corresponding size slot, and on the other side, it accepts nuts that allow tightening and loosening of screws and bolts. It is made of hardened metal, making it resistant to vibrations or impacts during work, allowing it to be connected to air tools as well. Additionally, it has a folding arm design, facilitating the approach to hard-to-reach points.
