1. A robot for tightening bolt nuts on a vehicle chassis, comprising:
a polyarticulated arm at the end of which is a nut tightening tool, the nut tightening tool comprising a socket having an orifice having a shape complementary to a nut;
a sleeve-shaped centering member arranged around the socket; and
a clamping screw for clamping the sleeve-shaped centering member around the socket, the clamping screw passing through two tabs facing each other and separated from one another by an axial slot;
wherein the sleeve-shaped centering member comprises a frustoconical surface which makes it possible, on contact with the nut, to reposition the nut tightening tool automatically to reposition the socket in the axis of the nut.
