Mercury OEM Nut 5-Pack — Part 68
A genuine Mercury OEM nut, sold in a convenient 5-pack. These precision-threaded nuts are factory-authorized replacements designed for use in Mercury and MerCruiser engine and drive assemblies where the parts diagram calls for Part 68. The 5-pack format makes it practical to stock spares or service multiple positions in a single job.
Key Features
- Genuine Mercury OEM nut — factory authorized
- Part reference: 68
- Sold as a 5-pack
- Precision-threaded for correct fit and torque retention
- Corrosion-resistant construction for marine environments
- Engineered to hold under vibration and thermal cycling
Fitment & Application
Use these nuts where the Mercury or MerCruiser parts diagram specifies Part 68 at the fastener position. Compatible with Mercury and MerCruiser marine engines and drive systems. Always verify the thread specification and diagram position against your engine model and serial number before ordering.
When to Replace
Replace when nuts are corroded, stripped, rounded, or have been removed from a critical assembly during service and cannot be safely reused. Fasteners in saltwater-exposed or high-vibration positions should be inspected at every service interval and replaced proactively.
Installation Notes
Confirm thread pitch and diameter against the diagram position before installation. Follow the Mercury service manual torque specifications for the specific assembly. Do not over-tighten — use a calibrated torque wrench and apply any locking compound specified in the service manual.

Parts Desk Insights
Best use case: The 5-pack format makes this the right buy when you are servicing an assembly that uses Part 68 in multiple positions, or when you want to keep spares on hand for a boat that sees regular saltwater use. OEM nuts are worth specifying over generic hardware in marine applications — the thread form, material, and any plating or coating are matched to the original assembly requirements. Always confirm the thread spec from the parts diagram before ordering, and replace any nut that shows corrosion or thread damage rather than reusing it.
