Axle Nut Socket 101mm for Mercedes-Benz & MAN Rear Axles

A 101mm axle groove nut socket for Mercedes-Benz and MAN rear axle applications where a standard socket is not suitable. Built for heavy-duty tightening and loosening work, it is intended for rear axle groove nuts on commercial vehicle setups that need the correct size and engagement.

Used in truck workshops, commercial vehicle service bays and heavier repair environments, this socket suits mechanics carrying out rear axle maintenance, axle strip-down work and refitting jobs. It is aimed at Mercedes-Benz and MAN 10/13t reduction, hypoid and trailer axle applications, including NR7/4 setups and Omnibus 0305 G and 0405 G. When working on high-torque axle nuts, using the proper groove nut socket helps with secure engagement and more controlled removal or installation.

The supplied dimensions include a 101mm stud size, 95mm inner diameter, 115mm outer diameter and 110mm height, with an 11.5mm stud width. Its internal square drive follows DIN 3121 / ISO 1174, which is useful when matching it with the correct drive arrangement for workshop use. There is also the option of using a sleeve locating tube where required. For regular heavy axle service work, having the correct Mercedes axle nut socket helps avoid poor fit on demanding jobs and keeps the right tool available for specialist rear axle maintenance.
