The M85049/31 is the grommet nut — also called an E-nut — that screws onto the rear of a connector shell when no environmental backshell is fitted. Its job is mechanical and sealing: it compresses the elastomeric grommet around the wire bundle and keeps the contact retention clip seated. Electroless nickel (N) is the cadmium-free finish, specified where cadmium is restricted and where repeated mating must not mark the shell.
