The Wacker Neuson 5100012085 is a genuine OEM Mushroom Head Screw designed for a broad range of Wacker Neuson single-drum soil compactors and tandem rollers. This screw is sourced directly from Wacker Neuson and carries the same part specification as the original hardware installed at the factory. Confirmed fitment spans the RC50, RC70, and RC110 single-drum soil compactor families, as well as the RD18, RD24, RD27, RD28, RD40, and RD45 tandem roller series — covering open ROPS, cab, DPF, and combination configurations. Verifying your machine's model number before ordering ensures a direct, hassle-free installation.
Key Features
- Genuine OEM Hardware Specification — Manufactured to the exact thread form, head profile, and material grade specified by Wacker Neuson, ensuring correct torque retention and seating behavior for this application.
- Direct Drop-In Replacement — Matches the original mounting pattern and mushroom head geometry so the screw seats flush and clamps correctly without reworking the surrounding hardware.
- Wide Cross-Family Fitment — Compatible with RC50, RC70, and RC110 single-drum soil compactors and the full RD18 through RD45 tandem roller lineup, including open, cab, DPF, and electric variants.
- Structural Integrity at the Joint — The broad mushroom head distributes clamping load over a wider surface area, resisting pull-through and maintaining a secure connection even under the continuous vibration loads produced by compaction equipment.
- Corrosion-Resistant Construction — Built to withstand the moisture, dirt, and mechanical stress typical of outdoor compaction and paving operations, supporting the service life of the joint it secures.
A mushroom head screw is a fastener distinguished by its wide, dome-shaped head, which spreads clamping force across a broader contact area than a standard hex or pan head screw. In compaction and roller equipment — where frames, covers, and panels are subjected to sustained vibration — this distributed load helps prevent the fastener from working loose or pulling through softer mounting surfaces. When this screw wears, strips, or goes missing, the component it secures can shift or rattle, potentially leading to misalignment, accelerated wear on adjacent parts, or panel damage. Replacing it with the correct OEM part restores the joint to its intended specification and keeps the assembly properly secured during operation.
