A tool for tightening or releasing a nut engaged on a screw-threaded shank, the tool comprising:
- a socket for engaging the nut;
- an adapter piece having a threaded bore for engaging the shank thread, wherein the socket is supported on the adapter piece so as to be free to rotate relative thereto;
