Description

Mercedes-Benz and MAN Clamp Nut Socket, 54mm

Brief Overview

This is a specialized clamp nut socket engineered for Mercedes-Benz and MAN heavy-duty vehicles. The 54mm capacity and multi-lobed (star/triangular) recess design target specific fasteners on these platforms. The tool complements a full suite of truck and bus maintenance sockets—pair it with heavy-duty 3/4-inch drive wheel nut sockets and commercial vehicle axle removal tools for complete drivetrain coverage.

Key Features

  • 54mm Clamp Nut Capacity: Precision-engineered hollow rectangular body sized for OEM clamp nut specifications on Mercedes-Benz and MAN powertrains.
  • Multi-Lobed Profile: Central star/triangular recess prevents slipping and provides positive engagement under high torque.
  • Reinforced Steel Construction: Thick-walled black-coated steel body absorbs impact loads typical of heavy-duty fastener removal.
  • Square/Hex Driver Socket: Female recess accommodates standard ratchet or breaker bar for controlled application of torque.
  • Rounded Corner Cavity: Internal geometry designed to match OEM clamp nut profiles without marring or deformation.

Business Advantages for Resellers

  • Niche-Specific Tool: Clamp nut sockets address a defined market segment (Mercedes-Benz/MAN technicians), reducing direct competition from generalist suppliers.
  • High Replacement Rate: Clamp fasteners are regularly serviced during drivetrain maintenance, creating recurring demand and repeat orders from fleet workshops.
  • Premium Positioning: Specialized OEM-compatible tools command higher margins than standard sockets and appeal to professional shops unwilling to compromise on fitment.
  • Fleet Workshop Essential: Heavy-duty vehicle fleets (logistics, construction, municipal) view these tools as non-negotiable inventory for scheduled maintenance.

Practical Application

This socket is purpose-built for removal and installation of clamp-style nuts found on Mercedes-Benz and MAN drivetrain assemblies. The multi-lobed profile eliminates cam-out and ensures secure engagement, critical when breaking loose heavily corroded or time-locked fasteners. The reinforced hollow design absorbs shock loads without cracking or deforming.


For fleet workshops and independent shops servicing Mercedes-Benz or MAN vehicles, this socket fills a specific—and essential—gap in your toolkit. Stock it for jobs involving drivetrain service, and establish yourself as the supplier shops trust for OEM-compatible specialist tools.
