The Honda 90071-MB0-000 Nut Washer (6MM) is a genuine OEM part designed for GX140, GX160, and GX200 horizontal shaft engines. As a direct Honda OEM component, this nut washer is manufactured to the same specifications as the original hardware installed at the factory. This part fits GX140, GX160, and GX200 engines — confirm your engine's serial number against the fitment table before ordering, as Honda updates hardware specifications at serial breaks.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this nut washer matches the original 6MM fastener in form and function, ensuring a proper fit without guesswork.
- Correct 6MM Sizing — the (6MM) designation is the variant identifier; confirm this matches the fastener size your engine requires before purchasing.
- Horizontal Shaft Engine Fitment — listed for GX140, GX160, and GX200 horizontal shaft engines; check your serial number against the fitment table, as Honda supersedes hardware at production breaks.
A nut washer is a combined fastener that integrates a washer flange into the nut body, distributing clamping load evenly across the surface it bears against and helping the fastener resist loosening under vibration. On Honda horizontal shaft engines like the GX140, GX160, and GX200, this type of hardware is used throughout the engine assembly to secure components reliably during operation. When a nut washer is missing, damaged, or the wrong size, the fastener it replaces can work loose, leading to component movement or leaks at that joint.
