Stop chasing mystery rattles and stripped Phillips heads—drop in Yamaha’s 90111-06144-00 hex-socket button bolt and lock your rig back to factory tightness. This humble fastener is an M6 × 25 mm stainless-steel button head built to secure everything from top-cowling latches and anode tabs to control-cable clamps on dozens of Yamaha outboards.

Why this little bolt earns a spot in your spares kit

• Low-profile 12 mm button head slides past wiring and fuel lines without snagging paint or skin.

• 4 mm internal hex drive lets you torque it decisively in tight quarters—no chewed-up Phillips slots.

• 316 stainless construction shrugs off salt spray and electrolysis, so the bolt you install this season looks the same next haul-out.

• Precisely rolled M6-1.0 threads match Yamaha’s alloy castings, preventing galling and cross-thread drama.

Practical payoff? A clean, flush finish that won’t work loose in chop, plus the confidence that your cowling, bracket, or accessory mount is held by the exact hardware Yamaha engineers specced. Toss a couple in the boat bag—because when a bolt vanishes at the ramp, having the right OEM replacement beats every creative fix.
