Steel: 6140CrV 44-48 HRC Nickel-plating A: 26 mm; B: 27 mm; C1: 9 mm; C2: 10 mm; Length: 190 mm A split wrench is necessary for servicing hydraulic and pneumatic systems. It is a 6-sided adjustable profile with a slot for fitting the wrench onto the pipeline. The profile of a split wrench is more massive and taller compared to an open-end wrench, which increases the contact area and reduces the risk of fastener deformation. The working profile of a split wrench is offset by 15º relative to the longitudinal axis, providing wider possibilities when working in confined spaces. The wrenches are made of chrome-vanadium steel. Nickel-plating with a protective lacquer layer ensures additional corrosion resistance.
