When working on a Mercury outboard or marine system, the right fastener makes all the difference. The Mercury M6 x 30 Screw (10-4000331) is designed for a precise, secure fit, ensuring your components stay tightly in place, even in high-vibration environments. Whether you're replacing a lost screw or swapping out a corroded one, this OEM Mercury part provides the durability and reliability you need.

Saltwater, heat, and constant movement take a toll on hardware over time. A standard screw might work for a while, but without marine-grade materials, corrosion can set in quickly. This factory-designed M6 x 30 screw is built to withstand harsh marine conditions, keeping your assembly secure without the risk of rust or stripping.

Installation is straightforward—just thread it in and torque it to spec. If you're performing routine maintenance, making repairs, or buttoning up a new project, using genuine Mercury hardware ensures everything stays exactly where it should.

Don’t risk using low-quality fasteners—stick with Mercury OEM parts for long-lasting performance on the water.
