Claim 16:
17. A method of installing nuts on a chrome flush valve comprising:
providing a tool, the tool having first and second members slidably and rotatably coupled to each other, the first and second members each having a handle portion and an end portion;
forming first, second and third jaw faces in the end portion of the first member, the first and second jaw faces forming a 120 degree angle, the second and third jaw faces forming a 120 degree angle such that the first, second and third jaw faces form three sides of a hexagon;
forming fourth and fifth jaw faces in the end portion of the second member, the fourth and fifth jaw faces forming a 120 degree angle, wherein at least four of the jaw faces conform to the shape of a hexagonal-shaped nut when the first and second members are squeezed together by a user with the jaw faces engaging the hexagonal nut;
forming a protrusion on one of the first and second members and a plurality of corresponding mating slots formed on the opposing first or second member, the mating slots being irregularly spaced from one another at locations along the opposing first or second member to accommodate specific sized nuts when the protrusion is seated in a given slot;
threading a nut on the flush valve;
placing at least the first, second, fourth and fifth jaw faces around the nut;
squeezing the handles of the first and second members to tightly engage four surfaces of the nut with the first, second, fourth and fifth jaw faces; and
applying torque to the tool to tighten the nut.
