Effortless loosening and tightening of screws - this is made possible by the new Cr-V ratchet open-end wrench from alca®. The open-end wrench makes it easy to reach tight screws or screws that are only accessible from the side. On the other side is a ratchet wrench with joint. Manufactured from chrome vanadium quality steel, with a fine toothing of 72 teeth, a back angle of five degrees and a jaw position of 15 degrees, the alca® quality product enables work to be carried out in the tightest of spaces. The set consists of five wrenches in sizes 8, 10, 13, 14 and 17 mm, so that any size of screw can be comfortably gripped. The five-piece set can be stored in the practical roll-up bag.
