The Honda 93403-06012-00 Bolt-Washer (6X12) is a genuine OEM fastener designed for GX360 horizontal shaft engines, ES6500 and EX5500 generators, and H4514, HT3813, and HT4213 lawn tractors. As a direct Honda replacement, this combined bolt-and-washer unit matches the original specification for each application it is listed under. Honda supersedes fasteners at production breaks, so confirm your machine's serial number against the fitment table before ordering. This part ships as a single piece incorporating both the bolt shank and integrated washer flange, eliminating the need for a separate loose washer during assembly.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, ensuring the thread pitch, shank length, and washer flange dimensions match the original hardware exactly as assembled at the factory.
- Integrated Washer Design — the captive washer flange distributes clamping load evenly across the mating surface, maintaining consistent torque retention without a separate washer component.
- Broad Fitment — listed for GX360 horizontal shaft engines, ES6500 and EX5500 generators, and H4514, HT3813, and HT4213 lawn tractors; use the fitment table to confirm the correct application for your unit.
- Serial Number Verification Recommended — Honda updates hardware specifications at serial breaks, so match your machine's serial number to the fitment table to confirm this is the right bolt-washer for your build.
A bolt-washer is a fastener that combines a hex bolt and an integrated washer flange into a single component. The washer flange spreads the clamping force over a wider area than a plain bolt head alone, helping to secure panels, brackets, and covers without the risk of a loose or missing separate washer. When the correct bolt-washer is not in place — or when one is damaged or stripped — the joint it secures can work loose under vibration, leading to misaligned components or accelerated wear at the fastening point. Using the correct OEM replacement ensures the joint is restored to its original clamping specification.
