Yamaha Bolt with Washer – 90119-10804-00

One bolt, a lot of responsibility. This genuine Yamaha M10 hex bolt comes with its washer permanently swaged in place, so the clamping load spreads evenly and stays put—no scrambling for loose hardware when you’re on the clock. Yamaha forges the bolt from high-tensile steel, then finishes it with a marine-grade zinc clear coat that shrugs off salt spray, humidity, and the constant thrum of an outboard at speed. Threads are cut to factory spec, matching the fasteners used on WaveRunner VX, GP1800, and other late-model Yamaha platforms, which means you hit torque spec once and forget about it.

Why keep a few on hand

• Captive washer: protects paint and trim, speeds up quick repairs.

• True OEM dimensions: exact thread pitch and shank length—no trimming or shimming.

• Corrosion defense: zinc-plus finish resists rust after months in a damp storage locker.

• Multi-tasker: ideal for seat decks, console brackets, locker lids, and other vibration-prone joints.

Replace stripped or missing hardware with this factory bolt, tighten to spec, and get back to enjoying smooth, worry-free days on the water.
