Wacker Neuson 5000011539 Screw M8 X 40 Socket Head

The Wacker Neuson Screw M8 X 40 Socket Head is a genuine OEM fastener designed for a wide range of Wacker Neuson vibratory rammers, reversible vibratory plates, and tandem rollers. This M8 x 40 mm socket head cap screw is sourced directly from Wacker Neuson and meets the exact dimensional and material specifications called out in the original equipment design. Compatible models span the BS50, BS60, BS70, BS52Y, BS65Y, BS30, and DS70Y rammer families, as well as DPU and BPU reversible plate compactor series including the DPU 4045, DPU 5045, DPU 5545, DPU 6055, DPU 6555, and BPU 3545A through BPU 6275 variants. Select RD-series tandem rollers are also covered. Sourcing the correct OEM fastener by part number ensures the screw's thread class, head geometry, and tensile grade match the original assembly requirement — critical in high-vibration compaction equipment where an incorrect substitute can back out or fail under load.

Key Features

• Genuine OEM Tensile and Thread Specification — Manufactured to Wacker Neuson's exact M8 x 40 mm thread pitch, length, and tensile grade, ensuring the fastener holds torque under sustained high-vibration operating conditions.
• Socket Head Drive for Controlled Torque Application — The internal hex (socket head) drive allows a torque wrench to be used in tight assembly clearances, delivering accurate clamping load without rounding the drive surface.
• Broad Cross-Family Coverage — A single part number covers BS-series gasoline rammers (BS50, BS60, BS70, BS52Y, BS65Y, BS30), DS70Y diesel rammers, DPU and BPU reversible vibratory plates, and select RD tandem rollers — simplifying parts inventory across a mixed fleet.
• Structural Integrity in High-Vibration Applications — In vibratory rammers and plate compactors, fasteners are subjected to continuous cyclical loading. A correctly rated OEM screw maintains joint preload and prevents component loosening or structural separation during operation.
• Direct OEM Cross-Reference — Part number 5000011539 maps directly to Wacker Neuson's own parts catalog, eliminating guesswork when ordering and confirming this is the same screw installed at the factory.

A socket head cap screw — commonly called an Allen bolt — uses an internal hexagonal recess to transfer torque from a hex key or socket driver to clamp two or more components together. In vibratory compaction equipment such as rammers and plate compactors, fasteners throughout the drivetrain, housing, and shoe assemblies are exposed to intense repetitive shock loads with every compaction stroke. If a screw is the wrong length, an incorrect thread class, or an inadequate tensile grade, it can stretch, back out, or shear under these conditions, leading to loose assemblies, component damage, or unsafe machine operation. Replacing a worn or missing fastener with the correct OEM-specified screw restores proper clamping force and keeps the assembly performing as designed.
