The Honda 90003-Z6L-010 Flange Bolt (6X106) is a genuine OEM fastener designed for GX630, GX660, GX690, GX700, and GX800 horizontal shaft engines, GXV630, GXV660, and GXV690 vertical shaft engines, and the EB10000 generator. As a direct Honda OEM component, this flange bolt is manufactured to the exact dimensions specified for these applications, ensuring a proper fit without the guesswork that can come with generic hardware. Confirm your machine's serial number against the fitment table before ordering, as Honda periodically supersedes fasteners at production breaks.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, so the thread pitch, shank length, and flange diameter match the original specification for these engines and the EB10000 generator
- Broad Fitment — listed for GX630, GX660, GX690, GX700, and GX800 horizontal shaft engines, GXV630, GXV660, and GXV690 vertical shaft engines, and the EB10000 generator; verify part number 90003-Z6L-010 against your serial number before ordering
- Correct Clamping Load — the integrated flange distributes clamping force evenly, reducing the risk of fastener loosening under the vibration loads typical of large-displacement Honda engines
A flange bolt combines a standard hex bolt with a built-in flanged washer at the head. The flange spreads the bearing load across a wider surface area than a plain bolt head, which helps maintain consistent clamping force on the joint it secures. When a flange bolt stretches, loosens, or is replaced with an incorrect size, the joint it holds can work loose under engine vibration, potentially leading to oil leaks, cover misalignment, or accelerated wear at the mating surfaces.
