Abstract
A drive tool that includes a drive socket. The drive socket includes alternating flutes and lobes and has a conical portion. The lobes, rather than being tapered in the conical portion of the socket, are each uniform in width as they progress to an end of the socket. The fact that the lobes are uniform in width in the conical portion of the drive socket provides for better engagement with the flutes of a conical section of a fastener.
