Steel: 6140CrV 44-48 HRC Nickel-plating A: 42 mm; B: 44 mm; C1: 13 mm; C2: 14 mm; Length: 230 mm A split wrench is necessary for servicing hydraulic and pneumatic systems. It is a 6-sided adjustable profile with a groove for fitting the wrench onto the pipeline. The profile of the split wrench is more robust and taller, unlike the open-end wrench, which increases the contact area and reduces the risk of fastener deformation. The working profile of the split wrench is offset by 15º from the longitudinal axis, which provides wider possibilities when working in confined spaces. The wrenches are made of chrome-vanadium steel. Nickel-plating with a protective lacquer layer provides additional corrosion resistance.
