ABSTRACT:
A tilt head wrench is provided having a handle with spaced-apart first and second openings each having a different geometrical shape. A tilt head includes a connector part through which extends a connector opening having a third geometrical configuration. A connector shaft extends through the first, second and connector openings. It includes a first end portion having a cross-sectional configuration that is engageable with the first opening and connector opening. The shaft includes a second end portion that is circular and permits free rotation of the head when positioned within the connector opening and second opening. Selective axial positioning of the connector shaft allows the tilt head to be in a locked or unlocked disposition.
