Wacker Neuson 5000164067 M6 Hex Head Flange Nut Zinc 8.8

The Wacker Neuson is a genuine OEM M6 Hex Head Flange Nut Zinc 8.8 designed for a broad range of Wacker Neuson tandem rollers, hydronic surface heaters, and related equipment. Sourced directly from Wacker Neuson, this hardware meets the exact grade 8.8 tensile strength specification called for in the original build. Confirmed fitment spans the RD7, RD7A, RD7H, RD7He, and RD7Ye walk-behind tandem roller series, the RD12, RD12A, and RD16 tandem roller series, HSH380 and HSH380S hydronic surface heater models, and E1250 hydronic heater variants. Keeping the correct OEM fastener in place ensures clamping loads stay within design tolerances across the service life of your machine.

Key Features

• Grade 8.8 Tensile Strength — Meets the medium-high strength classification required for structural and mechanical fastening points on Wacker Neuson equipment, preventing stretch or shear under operational load.
• Zinc-Plated Flange Design — The integrated flange distributes clamping force evenly without a separate washer, while the zinc coating provides corrosion resistance in outdoor and all-weather operating conditions.
• Genuine OEM Part — Produced to Wacker Neuson's exact material and dimensional spec for part 5000164067, ensuring thread pitch and head geometry match the original fastener precisely.
• Wide Multi-Machine Fitment — Compatible across the RD7, RD12, RD12A, and RD16 tandem roller families as well as HSH380 and E1250 hydronic surface heater models, making this a versatile stock item for mixed fleets.
• Maintains Structural Integrity — A worn, stripped, or under-spec nut on a roller or heater assembly can allow panels, guards, or mechanical components to work loose under vibration — using the correct grade fastener keeps assemblies secure through full duty cycles.

An M6 hex head flange nut is a metric fastener that combines a standard six-sided hex nut with a wide, integrated flange at its base. The flange acts as a built-in washer, spreading the clamping load across a larger surface area and reducing the risk of the fastener pulling through or damaging the mating material. On vibratory equipment such as tandem rollers, fasteners are subjected to continuous mechanical vibration during operation, making the correct grade and style of nut critical to keeping assemblies tight and preventing loosening over time. When a fastener is substituted with an incorrect grade or thread spec, clamping force degrades prematurely, which can allow covers, brackets, or operational components to shift — leading to accelerated wear or mechanical failure at those connection points.
