Steel: 6140CrV 44-48 HRC Nickel-plating A: 32 mm; B: 30 mm; C1: 8 mm; C2: 10 mm; Length: 200 mm. Combined wrench made of chrome-vanadium steel with a reliable 72-tooth ratchet mechanism in the open-end part. The direction of rotation of the ratchet is changed using a lever switch in the body of the wrench. The open-end part with the ratchet mechanism is inclined 10º from the longitudinal axis for ease of use. The ratchet wrench speeds up the loosening and tightening of fasteners in both normal and limited space conditions. It provides a high torque and a minimal return angle of 5º. Nickel-plating with a protective lacquer layer provides additional corrosion resistance to the ratchet wrench. The ratchet part of the wrench is not intended for stripping or forcefully pulling fasteners; for this, a box-end profile wrench or socket heads are used. You can also buy a set of combination ratchet wrenches with a switch.
