A multi-purpose tool may be comprised of a body having a gripping configuration on the outer surface of the body for long bolts and a lengthwise bore through the center of the body. The multi-purpose tool has a socket located at a first end of the body and a crown located at the second end of the body to receive various fasteners, such as flange and wing nuts. A multi-purpose tool may also be comprised of a body having a gripping configuration on the outer surface of the body and a lengthwise bore through the center of the body for a sleeve. The multi-purpose tool has a socket located in the sleeve at a first end of the sleeve and a crown located at the second end of the body to receive various fasteners, such as flange and wing nuts. The sleeve has a lengthwise bore through the center of the sleeve for long bolts or to accept a tool shaft. The tool shaft may accept various tool bits, and the tool shaft may be inserted into and engaged with the sleeve bore along its length. A cross hole extends in a substantially perpendicular direction through the center of the sleeve and the center of the body, respectively, which line up so the tool shaft may be inserted into and engaged with the sleeve bore for use as a T-handle.
