ABSTRACT:
A surgical instrument is disclosed having a male portion with a tapered hexagonal tip for engaging a socket head screw. A shaft operatively carries the male portion, for transmitting torque to the tip as it is matingly engaged with the screw. A metallic ring, mounted on the male portion, removably retains the tip matingly engaged within the socket head. The ring is formed with an oblique slit and is radially compressible, the ring presenting a substantially continuous circumferential surface that is in interference fit within the socket.
