An eye bolt has an elongate threaded shank having a longitudinal axis and a loop projection, such as a circular loop, extending from one end of the shank and a driving head rigidly mounted on the loop projection coaxially with the axis. To facilitate insertion into a material, the shank may include a self drilling and self tapping portion at the opposite end portion of the shank. A rotational driving force applied to the driving head causes the self drilling and self tapping portion to drill a hole in the material into which the threaded portion on the shank is screwed.
