The Honda 90102-VF9-003 Socket Bolt (5X20) is a genuine OEM fastener designed for UMK422 and UMK431 trimmers. Sourced directly from Honda, this bolt delivers the exact fit the original design calls for, with no guesswork on thread pitch or head geometry. It is listed for both the UMK422 and UMK431, so confirm your trimmer's serial number against the fitment table before ordering to ensure this is the correct specification for your unit.
Key Features
- Genuine OEM Fastener — manufactured to Honda's original specification, ensuring the correct thread form, head drive, and dimensions that aftermarket equivalents may not replicate exactly.
- Direct-Fit Replacement — engineered to drop straight in as a like-for-like swap, eliminating the need to source a substitute and risk mismatched sizing.
- Fits UMK422 and UMK431 Trimmers — listed under part number 90102-VF9-003 for Honda's UMK-series trimmers; check your serial number against the fitment table to confirm the correct application.
A socket bolt is a headed fastener driven by a hex key or Allen driver rather than a wrench, allowing installation in confined spaces where a standard bolt head may not clear surrounding components. On Honda UMK-series trimmers, fasteners like this one secure assemblies that must remain firmly in place through continuous vibration and outdoor use. A stripped, damaged, or missing bolt of the wrong size can allow components to work loose over time, so replacing worn or damaged hardware with the correct OEM part keeps the trimmer operating as intended.
