Wacker Neuson 1000343396 Bolt M8 x 20 Flanged 8.8 Zinc

The Wacker Neuson is a genuine OEM Bolt M8 x 20 Flanged 8.8 Zinc designed for the E3000 compact excavator series. As a sourced-direct OEM component, this bolt is manufactured to the exact grade, thread pitch, and flange geometry called out in the original Wacker Neuson bill of materials. Fitment spans multiple assemblies on the E3000, including engine, cabin and driver seat, and electrical system builds. When a fastener on a working machine needs replacing, matching the original specification keeps torque values, clamping loads, and corrosion resistance exactly where the engineers intended.

Key Features

• Correct Grade and Coating: — M8 x 20 flanged bolt rated at grade 8.8 with a zinc finish for corrosion resistance in outdoor and below-grade working conditions.
• Integrated Flange Design: — The built-in flange distributes clamping load across a wider bearing surface, reducing the risk of fastener pull-through without requiring a separate washer.
• Multi-Assembly Compatibility: — Verified for use across engine, cabin and driver seat, and electrical system assemblies on the E3000, making it a practical stock item for E3000 service work.
• OEM-Sourced Specification: — Supplied as a genuine Wacker Neuson part, so thread form, shank length, and zinc plating thickness match the original fastener exactly as installed at the factory.
• Electrical Assembly Safety: — When used in electrical enclosure and mounting applications, an incorrectly graded or undersized bolt can compromise grounding integrity; the 1000343396 meets the original spec for those installations.

A flanged hex bolt combines the function of a standard bolt and a washer into a single fastener — the wide, integral flange spreads the clamping force over a larger surface area and helps prevent loosening under vibration. In compact excavator applications like the E3000, fasteners in the engine bay, operator cabin, and electrical compartments are subject to constant machine vibration and environmental exposure, making correct grade and coating critical. A bolt that is under-spec in strength or surface protection can loosen, corrode, or fail under load, leading to component movement or loss of secure mounting in assemblies where stability is essential.
