The Honda 90007-PJ7-003 Bolt-Washer (10X105) is a genuine OEM fastener designed for GX640 horizontal shaft engines, H4518 lawn tractors, and H5518 multi-purpose tractors. As a direct Honda OEM component, this bolt-washer matches the exact dimensions Honda specified for these applications, ensuring a proper fit without any guesswork. Always confirm your machine's serial number against the fitment table, as Honda supersedes parts at specific serial breaks and correct identification matters for hardware this size.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt-washer meets the same dimensional specification as the original fastener installed at the factory
- Integrated Washer Design — the captive washer flange distributes clamping load evenly, which is exactly what Honda engineered into this fastener from the start
- Broad Fitment — listed for GX640 horizontal shaft engines, H4518 lawn tractors, and H5518 multi-purpose tractors; verify your serial number against the fitment table before ordering
- Correct Replacement — using the right OEM fastener by part number 90007-PJ7-003 protects thread engagement and maintains the clamping integrity Honda designed into the assembly
A bolt-washer is a fastener that combines a bolt and an integrated washer flange into a single component. The washer flange spreads the clamping force across a wider surface area than a plain bolt head alone, reducing the risk of the fastener pulling through or damaging the mating surface during torque-up. When a bolt-washer is worn, stripped, or replaced with an incorrect substitute, proper clamping load cannot be achieved, which can allow joined components to shift or loosen under the vibration loads that engines and tractors generate in normal use.
