Yamaha Hex-Socket Head Bolt – 91380-06020-00

Even the smallest fastener can make or break a day on the water. This genuine Yamaha M6 × 20 mm hex-socket bolt is the go-to fix when a bracket starts to wiggle or a panel refuses to stay put. The slim Allen head slides into cramped corners—think trim-tab plates, throttle-link brackets, and tight console mounts—where a box wrench has no chance. Yamaha cuts every thread to factory spec, for clean starts and accurate torque, then coats the high-tensile steel in a triple-layer marine zinc that shrugs off salt spray, fuel mist, and relentless vibration.

Why keep a few in your tackle box:

• Perfect OEM fit: 1.0 mm-pitch threads engage smoothly and stay put, eliminating cross-thread hassles.

• Rust-ready armor: multi-stage zinc finish fights corrosion long after lesser bolts turn orange.

• Sure-grip head: 5 mm Allen drive resists rounding, even when you’re wrenching at an awkward angle.

• Do-it-all hardware: secures cowling panels, battery trays, seat hinges—any joint that sees shock and shake.

Swap out tired or mystery hardware with this factory bolt, snug it once, and head back out knowing everything is locked down exactly as Yamaha intended.
