Abstract
An open adjustable wrench has an aligned handle and C-shaped head, the head being opened to the side. A moveable key slides in the head axially of the handle towards and away from a fixed gripping face on the upper end of the head. The key is adjusted in position by a threaded stem sliding in the keyway and itself advanced and retracted by rotation of a nut. The key and stem are detachably connected so that they can be removed from the wrench head for maintenance or replacement.
