Abstract: A socket and handle tool set facilitates the access of the socket to an obstructed fastener. Each socket provides a fastener receptacle to grip the fastener upon which the socket operates. Each socket splits open vertically along a vertical hinge. Specific embodiments provide a selectively latchable and unlatchable socket latch. Gear teeth are disposed around the circumference of at least a portion of the external perimeter of each socket. The gear teeth engage complimentary gear teeth that are disposed within the handle of the handle component of the tool set. The handle provides a socket holder and a socket drive mechanism disposed in the socket holder to engage the gear teeth of the socket. Additionally, the handle component of the tool set provides a driver tool receptacle distal from the socket handle to receive a driver tool to operate the socket drive mechanism.
