This 15mm Joker combination ratcheting wrench from Wera offers a unique holding function thanks to the metal plate in the jaw which reduces the risk of dropping nuts and bolts. The ratchet mechanism at the ring end enables the spanner to be used in very confined spaces. Made from high performance chrome molybdenum steel with a nickel-chrome coating. Features include a limit stop that prevents the open end from slipping over the nut, a holding function that allows fasteners to be held in the open jaw, and a jaw plate that grips into the fastener head to prevent slipping. It has the same size on both ends, bi-hex contact open jaw for extra torque, and an ultra-strong 80-tooth ratchet that needs only a 4.5-degree movement. The spanner does not have to be flipped and provides secure fastening even at high torque.
