The invention comprises a ratchet style flare nut wrench which incorporates an assembly to provide a torqueing function and ratchet effect. The assembly includes a wrench body capable of providing torque delivery through three rotating cylindrical cams which contact the nut. The cylindrical cams then rotate when reversing the direction of the wrench assembly so that a cutout portion of the cylindrical cams allows the nut points to pass by. Two cylinder cams are mounted on movable guide blocks which adjust the wrench for different size nuts. |
