The Honda 90310-769-M01 Hexagon Nut (5/16 NC) is a genuine OEM fastener designed for the MM52 multi-purpose tractor. Sourced directly from Honda, this replacement nut matches the original specification installed at the factory, ensuring a proper fit without modification. If you're restoring or servicing an MM52, confirming part number 90310-769-M01 against your machine's serial number in the fitment table is the best way to be certain this is the correct fastener for your application.
Key Features
- Genuine OEM Honda Fastener — supplied directly from Honda's parts catalogue, matching the original nut used in MM52 multi-purpose tractor production
- 5/16 NC Thread Form — cut to a National Coarse (NC) thread profile, so it engages cleanly with the mating component without risk of cross-threading or forced fit
- Direct OEM Replacement — verify part number 90310-769-M01 against your MM52 serial number in the fitment table before ordering, as Honda periodically supersedes fastener part numbers across production runs
A hexagon nut is a standard threaded fastener used throughout the MM52 multi-purpose tractor to secure components at assembly points across the machine. The 5/16 NC designation indicates the thread diameter and pitch, which must match the bolt or stud it pairs with to achieve correct clamping force. Using the correct OEM nut ensures the fastener torques to spec and holds components firmly without backing off during operation — a worn, stripped, or incorrect nut can allow assemblies to loosen over time, leading to component movement or damage.
