The Wacker Neuson is a genuine OEM M12 Hex Head Flange Nut Zinc 8.8 designed for the RD12 and RD16 series tandem rollers, including the RD12-90, RD12A-90, RD16-90, and RD16-100 models. As a factory-sourced fastener, this nut is manufactured to the same specification as the hardware installed at the point of original assembly, ensuring a direct, like-for-like replacement. Grade 8.8 construction and zinc plating deliver the mechanical strength and corrosion resistance required for the demanding environments these rollers operate in. Whether you are servicing the hydraulic system, drum assembly, or seat components, having the correct fastener on hand keeps the job moving.

Key Features

  • Grade 8.8 Tensile Strength — Medium-carbon steel at grade 8.8 rating provides the clamping force and shear resistance needed in structural and drivetrain fastener positions on asphalt compaction equipment.
  • Zinc-Plated Finish — Electroplated zinc coating resists rust and surface corrosion, protecting fastener integrity through repeated exposure to water, asphalt, and outdoor working conditions.
  • Genuine OEM Part — Sourced directly from Wacker Neuson, this nut matches the exact thread pitch, flange diameter, and head dimensions specified for the original assembly — no guesswork on fitment.
  • Flanged Hex Head Design — The integrated flange distributes clamping load over a wider surface area, reducing the risk of fastener pull-through or surface damage on mating components without requiring a separate washer.
  • Broad RD-Series Compatibility — Confirmed fitment across multiple RD12 and RD16 tandem roller configurations, including solid ROPS, foldable ROPS, and hydrostatic variants used in asphalt and soil compaction applications.

A hex head flange nut is a standard but critical fastener that combines a conventional hex nut with an integrated load-spreading flange at its base. The flange acts as a built-in washer, distributing clamping pressure evenly and helping to prevent loosening under vibration — a particularly important characteristic on compaction rollers that generate continuous oscillation during operation. When a fastener of this type is missing, stripped, or substituted with an incorrect grade or thread pitch, it can result in joint loosening, structural misalignment, or component failure in the assemblies it secures, including drum and hydraulic system mounting points.
