The Honda 90003-ZE2-000 Hexagon Bolt (7/16-20UNF) is a genuine OEM fastener designed for Honda GX240, GX630, GX660, GX690, GXV630, GXV660, and GXV690 engines. As a direct Honda OEM component, this bolt is manufactured to the exact thread specification — 7/16-20UNF — required by the engines it serves, ensuring proper torque retention without the guesswork of an off-the-shelf substitute. Confirm your engine's serial number against the fitment table to verify this is the correct bolt for your application before ordering.
Key Features
- Genuine OEM Thread Specification — cut to Honda's 7/16-20UNF thread form, so it engages cleanly with the tapped bore it was engineered for without risk of cross-threading or stripping
- Direct OEM Replacement — sourced directly from Honda, this bolt carries part number 90003-ZE2-000 and drops in as a like-for-like replacement with no reworking of the mating hardware
- Broad Engine Fitment — listed for Honda GX240, GX630, GX660, GX690, GXV630, GXV660, and GXV690 engines; Honda supersedes fasteners at serial breaks, so always cross-reference your engine's serial number against the fitment table
A hex bolt is a threaded fastener driven by a wrench on its six-sided head, used throughout Honda's engine assemblies to clamp components together under a specified torque load. Using a bolt with the correct thread pitch and diameter — in this case 7/16-20UNF — is essential: a mismatched fastener will not achieve proper clamping force, which can lead to joint movement, fluid leaks, or component damage over time. Replacing a worn, stripped, or missing bolt with the correct OEM part restores the integrity of the joint and keeps the engine running as Honda intended.
