ABSTRACT
Low profile wrenches are adjustable to fit on a number of bolt patterns. For instance, one wrench may be used on a flange with twelve 17/a in. bolts or one with forty-eight 17/s in. bolts simply by adjusting the position of the reaction device so the hydraulic cylinder at midstroke remains in the same 90° angle orientation with respect to the wrench head. (See Fig. 5.)
