Wacker Neuson 5100012780 Mushroom Head Screw

The Wacker Neuson 5100012780 is a genuine OEM Mushroom Head Screw designed for the RC and RD series of compaction machines, covering single-drum soil compactors and tandem rollers across a wide range of configurations. As a genuine OEM component, it is manufactured to the exact material and dimensional standards set by Wacker Neuson, ensuring a direct, correct-fit installation every time. 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, including smooth-drum, padfoot, cab, ROPS, DPF, and electric variants. Sourcing part number 5100012780 directly guarantees you receive the correct specification for your machine.

Key Features

• Genuine OEM Material Spec — Manufactured to Wacker Neuson's exact head geometry and thread specification, so the mushroom head seats and clamps correctly without distortion or stripping.
• Direct Drop-In Installation — Thread pitch and shank diameter match the original fastener position, allowing installation without rethreading or modification to the host assembly.
• Broad Compaction Equipment Coverage — A single part number covers RC50, RC70, and RC110 single-drum soil compactors and RD18 through RD45 tandem rollers, including padfoot, cab, ROPS, DPF, and electric variants.
• Maintains Clamping Integrity — The wide mushroom head distributes clamping load across a larger surface area, preventing pull-through on panels or guards and keeping assemblies securely located under continuous vibration.
• Vibration-Environment Rated — Designed to retain holding force in the high-vibration operating environment of compaction equipment, where standard fasteners can work loose over time.

A mushroom head screw is a fastener characterized by its wide, low-profile domed head, which spreads clamping force across a broader contact area than a standard hex or pan head screw. On compaction equipment like soil compactors and tandem rollers, this style of fastener is commonly used to secure panels, guards, covers, and trim components that are subject to continuous vibration during operation. When a mushroom head screw fails — through corrosion, thread damage, or head shear — the panel or guard it secures can become loose, rattle, or detach entirely, which can lead to secondary damage to surrounding components or create a hazard on the worksite. Replacing a worn or damaged screw with the correct OEM part maintains the structural integrity of the assembly and keeps covers and guards properly positioned.
