Groove Nut Socket 105mm ID for Mercedes Actros Rear Axle

This Mercedes Actros groove nut socket is made for rear axle service where a standard socket is not suitable. Built for HL and HL8 hypoid axle applications, it gives the correct fit for tightening and loosening heavy-duty axle nuts under high torque.

Used in commercial vehicle workshops, fleet maintenance, roadside repair work and specialist truck servicing, this socket suits mechanics working on Actros rear axles that need the proper tool for safe, controlled removal and refitting. When carrying out axle repairs or routine rear axle maintenance, the dedicated groove nut design helps with secure engagement on the nut rather than relying on a workaround.

The socket has a 105mm inner diameter, 125mm outer diameter and an overall height of 180mm, giving the depth needed for rear axle nut access. A 60mm locating tube helps it sit correctly in use, while the 3/4in internal square drive is made to DIN 3121 / ISO 1174 dimensions for compatibility with suitable drive tools. Stud measurement is 116.5mm with a 10mm stud width. For regular commercial vehicle axle work, using the correct Mercedes axle nut socket helps avoid poor fit and gives more confidence when dealing with stubborn or high-torque fasteners.
