Wacker Neuson 5100011584 Mushroom Head Screw

The Wacker Neuson 5100011584 is a genuine OEM Mushroom Head Screw designed for the RD-series tandem rollers and RC110 single-drum soil compactors. As a factory-sourced component, it is manufactured to the exact material grade, thread specification, and head geometry Wacker Neuson requires for proper assembly and retention. Fitment spans the full RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families as well as the RC110 and RC110P single-drum compactor line, covering both walk-behind and ride-on articulated configurations. Verifying your machine model against the fitment list before ordering ensures a correct, direct swap with no additional hardware needed.

Key Features

• Genuine OEM Thread and Head Spec — Sourced directly from Wacker Neuson, this screw meets the exact thread pitch, shank diameter, and mushroom-head profile required for secure fastening in the original mounting location.
• Drop-In Replacement — Installs into the factory threaded bore without rework; the mushroom head profile seats flush and applies the correct clamping load as originally designed.
• Broad Tandem Roller Coverage — Fits the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller families across standard, combination, canopy, cab, DPF, and electric variants, plus the RC110 and RC110P single-drum compactors.
• Structural Integrity Under Vibration — Tandem and single-drum rollers generate continuous high-frequency vibration; a correctly spec'd OEM screw resists backing out and maintains clamping force across extended operating cycles.
• Wide Variant Compatibility — Covers US-market, ROPS, CAB, DPF, and .3-revision models within the RD and RC110 families, making this a single-part solution across a large portion of the Wacker Neuson roller fleet.

A mushroom head screw is a fastener characterized by its broad, low-profile domed head, which distributes clamping load across a wider surface area than a standard hex or socket head cap screw. This geometry is typically used in assemblies where a large bearing surface is needed against soft, thin, or layered material — preventing pull-through or surface deformation under load. On vibratory compaction equipment such as tandem rollers and single-drum compactors, fasteners are constantly exposed to machine-generated vibration; using a correctly dimensioned OEM replacement ensures the joint maintains its designed preload and does not loosen or fail prematurely during operation.
