A knob that works with 1/2" sockets. It is used to drive sockets, and at the same time allows you to act on the socket and bolt with more torque than in a traditional ratchet. The higher torque is achieved by the long arm of the knob (the torque increases in proportion to the length of the arm). The product is made of bend- and fracture-resistant CrV 50BV30 chrome vanadium steel. The hinged oxidized stem has a ball that locks and fixes the socket during operation.
