Combination spanners Ratchet ring and open-end wrenches for ratcheting loosening or quick tightening of screws and nuts in one go without setting them with the ring ratchet. On one side an open-end wrench or open-end wrench with 15 degree offset, on the other side a ring spanner of the same width with built-in ratchet mechanism with special advantages: Ratchet with fine teeth: 72 teeth = only 5 degrees minimum swivel angle. Left and right rotation is achieved by simply turning the wrench and not by means of an annoying switch lever, which often gets moved unintentionally. Despite the ratchet, the wrenches are very narrow. This makes the tools particularly suitable for use in confined spaces. 12-edge ring with flank drive, ie the drive is no longer via the corners of the screw head, but on the flanks, which means that a much higher power transmission is achieved and the edges of screw heads and nuts are protected. Drop-forged from chrome-vanadium steel, specially hardened, highly polished, nickel-plated and hard chrome-plated. Very high torque transmission, exceeds DIN requirements.
