A torque multiplier consists of a wrench or a set of wrenches, to be used with a torque wrench to increase the capacity of a torque wrench by specific ratios, each having an elongated, non-extensible, straight shank with a laterally extended drive stud at one end and a laterally disposed stud socket at the other end. The studs of each wrench can be made to fit the sockets of each other wrench in the set, so that they can be mounted end to end in a straight line to multiply the leverage, torque foot pounds, or mechanical advantage of a single wrench of the set. The studs, or sockets, may be square or hexagonal and may be of the ratchet type.
