ABSTRACT:
A ratchet screwdriver and method of making same wherein there is a handle and there is a ratchet gear and pawls inside the handle. An adjuster is inside the handle and is movable by a tool extending into the handle for positioning the adjuster relative to the gear and thereby eliminating play between the gear and the handle. Ball bearings are interposed between the handle and the gear and the bearings rotatably support the gear and transmit the anti-play forces that act on the gear.
