<p>A tool (1) suitable for rotating a threaded fastener on a screw thread comprises at least two component parts (3, 5) which can be separably connected together using connection means (17, 22) in order to assemble the tool (1). Each component part comprises at least one bearing surface (7) for acting upon the threaded fastener to rotate it relative to the screw thread. The tool (1) can be assembled around the threaded fastener, to bring the said bearing surfaces (7) into contact with it, and the tool can be disassembled into the component parts (3, 5) to allow removal from the threaded fastener.</p> |
