发明名称 Oil drain plug wrench
摘要 An oil drain plug wrench is provided to enable a user to more easily remove and install an oil drain plug. The wrench includes a rotor with two cavities on opposite sides of a rotor. When either of the cavities engages a workpiece, the wrench is capable of applying torque to the workpiece in a first rotational direction and ratcheting in a second rotational direction. A flange is provided on the outer diameter of the rotor to allow a user to remove or install an oil drain plug by hand.
