Steel: 6140CrV 44-48 HRC Nickel plating A: 32 mm; B: 31 mm; C1: 7 mm; C2: 10 mm; Length: 200 mm Combined key made of chrome-vanadium steel with a reliable 72-tooth ratchet mechanism in the spanner part, designed as a swivel joint. The ratchet spanner speeds up the loosening and tightening of fasteners in both normal and limited space conditions. The minimum angle of return for the key is 5º. Nickel plating with a protective lacquer layer provides additional corrosion resistance for the ratchet key. The ratchet part of the key is not intended for stripping or forcibly pulling fasteners. For this purpose, a socket or box wrench is used. You can also buy a set of combined ratchet hinged keys.
