Abstract
A driver for screws, bolts and the like which have a socket for receiving the bit of a driver, in which a tapered holding section between the bit and the shaft of the driver serves to hold an article by frictional engagement with the opening edge of the socket when the bit is engaged in the socket for turning the article. The bit is shorter than the depth of the socket, and the holding section expands sufficiently away from the bit so as to make frictional contact with the edge of the socket when the bit is engaged in the socket.
