Yamaha Bolt with Washer - 90119-10804-00 When a single bolt has to hold its own against vibration, salt spray, and full-throttle chop, you reach for Yamaha's OEM hardware. This M10 hex bolt arrives with a captive washer already pressed on, so the load spreads evenly and stays tight without hunting for loose hardware. Forged from high-tensile steel and treated with a marine-grade anti-corrosion coating, it's the same spec Yamaha installs at the factory on WaveRunner VX, GP1800, and other late-model platforms-meaning threads start clean, torque values stay true, and fasteners don't back off mid-season. Why it's worth stocking a few spares: Integrated washer: protects painted surfaces and saves time during splash-and-dash fixes. Exact OEM fit: correct thread pitch and shank length-no cutting, shimming, or guessing. Salt-ready finish: zinc-plus clear coat resists rust even after months in a humid locker. Versatile use: secures seat decks
