The Honda 93403-06028-08 Bolt-Washer (6X28) is a genuine OEM fastener designed for GX22, GX31, and GX35 horizontal shaft engines, along with the HHE31 stick edger, HHT31 trimmer, UMK422 trimmer, and UMK431 trimmer. As an OEM component, this bolt-washer is manufactured to Honda's exact specifications, ensuring correct thread engagement and clamping load wherever it is used across these machines. Always verify your unit's serial number against the fitment table to confirm this is the right part for your application.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, so thread pitch, shank length, and integrated washer geometry match the original fastener exactly
- Broad Honda Fitment — listed for GX22, GX31, and GX35 horizontal shaft engines as well as HHE31, HHT31, UMK422, and UMK431 handheld power equipment
- Confirm by Serial Number — Honda updates fastener specifications at production breaks, so cross-check your machine's serial number against the fitment table before ordering
A bolt-washer is a single-piece fastener that combines a bolt with an integrated washer flange. The washer flange distributes clamping load over a wider surface area than a plain bolt head alone, helping to secure components firmly without the risk of a loose washer migrating or being omitted during reassembly. Using the correct OEM fastener with the right thread size, length, and flange diameter ensures proper torque retention and keeps assembled components seated correctly through the vibration cycles these engines and power tools generate.
