Everything that a wrench has to do, and a whole lot more: unique holding function, thanks to the metal plate in the jaw, reduces the risk of dropping nuts and bolts. Replaceable metal plate in the jaw secures nuts and bolts with its extra hard teeth and reduces the danger of slipping. Integrated limit stop prevents any slipping around the bolt head and allows higher torque to be applied; double-hex geometry makes for a positive connection with nuts or bolts and reduces the risk of slipping. Return angle of only 30° at the open end to avoid time consuming flipping of the wrench during fastening jobs.
