ABSTRACT:
This drawing holder nut wrench is made up of a rounded hand grip, a socket body, a socket, and a way to limit torque. The torque is limited by the small size of the hand grip. The hand grip has smoothly rounded projections on it to give a comfortable grip and a shallow mortise in its top shaped to match and aligned with the socket beneath it. The mortise reveals the orientation of the socket beneath without having to turn the wrench over to look at the socket itself. The socket has a generally elongated hexagonal cross section and is a straight sided hole cut upwardly into the bottom of the socket body.
