The Wacker Neuson is a genuine OEM Nut M20, Hex, 8.8, Zinc Plated designed for RD16 and RD27 series tandem rollers. Sourced directly from Wacker Neuson, this fastener meets the exact grade, thread pitch, and surface treatment specified for the original assembly. It is confirmed for use across multiple RD16-90, RD16-100, RD27-100, and RD27-120 configurations, including Pro, Basic, and Tier 4 Final variants. When a fastener of this grade is needed to hold structural or drivetrain components at load, using the correct OEM specification is the straightforward choice.
Key Features
- Grade 8.8 Tensile Rating — Medium-high strength steel construction rated to Class 8.8, delivering the clamping force and torque resistance required for heavy-duty roller assemblies operating under continuous vibration.
- Zinc-Plated Corrosion Protection — Factory-applied zinc plating creates a barrier against rust and oxidation, extending service life in outdoor and wet jobsite conditions typical of compaction work.
- M20 Hex Form Factor — Standard M20 hex profile installs with common tooling already on the machine, with no adapter or special socket required.
- Genuine OEM Specification — Manufactured to Wacker Neuson OEM tolerances, ensuring the correct thread engagement depth and seating dimension for the original fastener location.
- Broad RD16 and RD27 Series Coverage — Fits RD16-90, RD16-100, RD27-100, and RD27-120 models across Hydrostatic, Pro, Basic, and T4F variants, making it a go-to stock fastener for fleets running multiple RD-series rollers.
A hex nut of this specification is used to secure structural, mechanical, or drivetrain fastening points on ride-on tandem rollers where high clamping loads and vibration resistance are required. The Class 8.8 grade designation defines the fastener's minimum yield and tensile strength, ensuring it will hold a specified preload without stretching or loosening under the cyclical stress generated by vibratory compaction. When a fastener of this type fails, stretches, or is replaced with an incorrect grade, the joint it secures can lose preload, leading to movement, wear, or component damage in the assembly it holds together. Using the correct OEM-specified grade and plating ensures the replacement performs identically to the part it replaces.
