The Clamp-On Wrench is a knurled, easy-to-grip collar that is clamped around standard pipe, a shaft or hex nut and is then tightened with a twist of the wrist. Permitting rapid tool changes, this compact wrench can be hand tightened but still allows for conventional wrenches when high torquing is required. It is manufactured from anodized aluminum for an attractive, durable finish.
