Abstract: An anchor eye-bolt for use in strengthening a mine roof as well as for supporting mine installation below the roof. The anchor eye-bolt of the present invention comprises broadly an elongated stem having on a first end thereof a threaded portion for engaging into an expansion-type anchor shell, and a polygonal bolt head forming a second end thereof. The polygonal bolt head comprises a circular pressure bearing surface on a first side thereof adjoining the stem, and an eyed projection extending from a top surface thereof. The circular pressure bearing surface preferably has a diameter as large as an across-corner dimension of the polygonal bolt head. The eyed projection preferably has a width similar to an across-flat dimension of the polygonal bolt head. A thickness of the eyed projection is preferably substantially a same dimension as a diameter of the stem. In another aspect of the anchor eye-bolt of the present invention, there is provided a tension washer used in combination with that anchor eye-bolt.
