Abstract

In an adjustable box wrench for gripping hexagonal nuts and bolt heads, the wrench consists of three movable parts.
The first part consists of a hexagonally shaped head, open top and bottom, permanently attached to a hollow tubular shaft which is attached to a handle. The extremity of the head has two gripping surfaces at 120° to one another, forming the fixed jaw of the wrench. The second part is a movable jaw with simi-lar oppositely placed gripping surfaces permanently attached to a rod which passes through the tubular shaft and is threaded on the end where it leaves the tubular shaft and enters the handle.
The third movable part is a knurled adjustment nut which is restricted in its forward and backward movement but which engages the threaded end of the rod and thus can advance and retract the movable jaw. The invention places the adjustment screw in the handle instead of in the head of the wrench, thus reducing the bulkiness in the head while also allowing the user to operate the wrench with one hand. The adjustment nut can be manipulated by the thumb and forefinger while firmly gripping the handle with the rest of the hand. Since the parallel lateral surfaces of the movable jaw are slidably confined by the two parallel inner surfaces of the sides of the head, the jaws of the wrench can be extended downward to engage a hexagonal nut or bolt head which is recessed.
