The Wacker Neuson Hexagon Screw is a genuine OEM hexagon screw designed for the RD18, RD24, RD28, RD40, and RD45 series tandem and vibration rollers. As a direct OEM replacement, this screw is manufactured to the exact dimensions and material grade specified by Wacker Neuson, ensuring a correct, secure fit every time. The covers an extensive range of configurations across the RD roller lineup, including standard, combination, open-drum, DPF, and electric variants. Cross-reference your model number against the fitment list to confirm compatibility before ordering.
Key Features
- Exact OEM Thread Form and Grade — Manufactured to the precise thread pitch, head geometry, and material grade called out in the Wacker Neuson parts system, so torque loads are carried correctly without risk of stripping or loosening.
- Direct Drop-In Installation — Matches the original fastener profile exactly, dropping into existing threaded bores without reworking or re-tapping required.
- Broad RD Series Coverage — A single part number serves RD18, RD24, RD28, RD40, and RD45 roller families across standard, combination, open-drum, DPF-equipped, and electric configurations.
- Structural Holding Power — A correctly specified screw maintains the clamping force that holds critical roller assemblies together under continuous vibration load; an undersized or incorrect fastener can work loose during operation and compromise machine integrity.
- Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, carrying the same part number — 5100029558 — used by authorized Wacker Neuson service dealers worldwide.
A hexagon screw is a standard hex-head fastener used throughout heavy compaction equipment to clamp, secure, and align structural and mechanical components. In tandem roller applications, these screws are subjected to constant vibration and dynamic load cycling, making correct material grade and thread specification critical — an incorrect or substandard fastener can back out under vibration, leading to loosened assemblies, accelerated wear on mating components, or unexpected mechanical failure in the field. Replacing a worn or damaged fastener with the correct OEM-specified part restores the designed clamping force and keeps the machine operating as intended.
