The Wacker Neuson is a genuine OEM Washer M8 Hardened Black Type 200 designed for G25 series portable generators and LTW20 series light towers. As a direct OEM replacement, is manufactured to the same specification as the original hardware, ensuring correct seating, clamping load, and corrosion resistance across the full range of compatible units. Fitment spans G25 generator variants — including Standard, Cold Weather, Custom, Extended Run, and 600V Switchable configurations — as well as LTW20Z1 and LTW20Z3 light tower models in multiple Tier 4i and Tier 4 Final builds.
Key Features
- Hardened Steel Construction — The M8 hardened profile resists compression set and surface deformation under bolt load, maintaining joint integrity in high-vibration generator and light tower applications.
- Black Finish for Corrosion Resistance — The Type 200 black surface treatment provides added protection against rust and oxidation, important for equipment that operates outdoors or in cold-weather environments.
- Exact OEM Specification — Sourced directly from Wacker Neuson, this washer matches the original hardware dimensions and hardness grade, so it drops into place without modification.
- Broad G25 and LTW20 Compatibility — Confirmed for G25 Mobile Generators (Standard, Cold Weather, Custom, Extended Run, 600V, and Battlefield variants) and LTW20Z1 / LTW20Z3 light towers across Tier 4i and Tier 4 Final emission levels.
- Maintains Fastener Integrity — A worn or undersized washer can allow bolt heads to pull through mounting surfaces or allow fasteners to loosen under load; replacing with the correct hardened washer restores proper clamping force.
A hardened washer distributes the clamping load of a fastener across a wider surface area, preventing the bolt head or nut from embedding into or damaging the mating material. In generator and light tower assemblies — where components are subject to continuous engine vibration and varying thermal cycles — using a washer with the correct hardness grade and outer diameter is critical to keeping fastened joints secure over time. When a washer is missing, worn flat, or replaced with an incorrect grade, fasteners can back out or the clamped surfaces can shift, leading to structural looseness or component damage.
