ABSTRACT:
A band clamp tightening tool comprising a cylindrical body, having at one end an internal bore adapted to pressfit the tool over the hex shaped head of a hose clamp adjustment screw, to which a combination crank/thumbscrew element has been affixed, said element being formed by passing a metal rod through a transverse aperture in the tool body, bending said rod to form a crank arm and a crank handle on one side of the body, and, on the opposite side of the tool body bending said rod to form a semicircular loop or thumbscrew element in the plane of the crank handle. In the use of this tool when attached to a hose clamp, the crank handle is rotated between the thumb and index finger to take up any slack in the band of the clamp, and to tighten the clamp the index finger is moved across the tool body to the thumbscrew loop, and the tool is turned as a large thumbscrew.
