ABSTRACT:
An access plug is provided for use in oil pans, transmissions and other fluid containers of equipment and the like. The access plug is weight imbalanced along the longitudinal axis to prevent inadvertent rotational movement of the access plug as may occur from vibrational forces when the plug is not properly tightened. By designing the plug with such an imbalance, the plug will terminate its rotation as the weighted half reaches the lowermost point during removal rotation and will so remain, preventing complete removal and rapid fluid loss.
