A plastic coated handle is use to provide leverage in applying torque to the elongated hex-head nut (wing knob). At the opposite end of the wrench is a common hexagon shaped hole for loosening and tightening a 5/16" hex-head nut. Located closer to the elongated hexagon shaped hole than to the common hexagon shaped hole is a vertical offset.
