Abstract: An adjustable head wrench with an elongated generally straight offset handle and a stationary jaw fixed to the handle. A movable jaw rides in a bore hole and slot within the stationary jaw with a worm gear. The worm gear in turn fits into a bore hole in the movable jaw and engages internal teeth of the movable jaw with its outer helical gears. At front end of the worm gear threads mount an external adjuster outside of the stationary jaw and wrench head. This rotatable adjuster is used to rotate the worm gear which causes the distance between the object engaging surfaces of the stationary and movable jaws to vary. To retain the adjuster in place and prevent unwanted rotation with respect to the stationary jaw, a biased ball bearing mounted in a cavity of the stationary jaw is used to engage the outer surface of the adjuster.
