Wacker Neuson 5000129022 Countersunk Screw M6X12-8.8

The Wacker Neuson is a genuine OEM Countersunk Screw M6X12-8.8 designed for the RD7H-ES tandem roller series and a broad range of DPU and DPS reversible and single-direction vibratory plate compactors. As a factory-sourced fastener, part meets the exact dimensional and grade specifications called out in Wacker Neuson's assembly drawings, ensuring consistent clamping force and flush-seating performance. This screw is confirmed to fit numerous DPU and DPS models — including the DPU 2440H, DPU 2540H, DPU 2550H, DPU 2560H, DPU 3050H, DPU 3060H, DPU 3070H, DPU 3750Hts, DPU 3760Hts, DPS 1850H, DPS2050H, DPS3060Hv, and the RD7H-ES — making it a widely applicable service part for mixed-fleet operators. Verify your machine's serial number against your parts manual before ordering to confirm this is the correct specification for your unit.

Key Features

• Grade 8.8 Tensile Rating — The 8.8 property class designation confirms this screw meets medium-high-strength steel standards, providing the clamping load required for structural and housing fastening on high-vibration compaction equipment.
• Flush Countersunk Profile — The countersunk head seats fully flush with the mating surface, preventing protrusion that could interfere with adjoining components or protective covers during reassembly.
• Genuine OEM Sourcing — Supplied directly through the Wacker Neuson parts network, this fastener matches the thread pitch, shank length, and head angle specified in the original machine design — no guesswork on sizing.
• Broad Cross-Fleet Compatibility — A single part number covers DPU 2440H through DPU 3760Hts vibratory plates, multiple DPS asphalt and basic plate variants, and the RD7H-ES tandem roller, making it efficient to stock for mixed Wacker Neuson fleets.
• Vibration-Environment Integrity — Fasteners on vibratory compaction equipment are subject to constant cyclic loading. Using the correct grade and geometry replacement prevents progressive loosening, housing damage, or component separation under operating conditions.

A countersunk screw is a threaded fastener with a tapered head designed to sit flush with — or below — the surface of the material it secures. On vibratory compaction equipment such as the DPU and DPS plate compactor series and the RD7H-ES tandem roller, countersunk fasteners are used where a raised fastener head would obstruct cover panels, guards, or mating assemblies. The M6X12 designation indicates a 6 mm thread diameter and 12 mm shank length, making it specific to lighter structural or housing attachment points rather than primary load-bearing joints. When a countersunk screw fails — through stripping, corrosion, or improper torque — the secured component can shift, rattle, or detach, potentially exposing internal parts to contamination or causing accelerated wear on adjacent surfaces.
