Abstract
A surgical speed wrench useful in installing spinal implant devices is provided with a thin profile and means for holding a part to be installed with a threaded fastener. The thin profile is achieved by a socket formed directly in a torque transmitting gear. The threaded fastener head is received directly in the socket and no other tool or adapter is required which would increase the profile. The holding means includes two extending arms terminating in spherical members which biasly engage a bore in the part to be installed. With the part thus held, the threaded fastener is received in the wrench socket and may be started and driven without the surgeon using his or her fingers or other instruments.
