The Honda 90304-769-M01 Jam Nut (5/8 NC) is a genuine OEM fastener designed for the MM52 multi-purpose tractor. As a direct Honda OEM part, it meets the exact thread specification — 5/8 NC (National Coarse) — called out in the MM52 parts catalog. Sourcing the correct jam nut by part number 90304-769-M01 ensures proper thread engagement and eliminates guesswork when reassembling.
Key Features
- Genuine OEM Fit — sourced directly from Honda, this jam nut matches the exact 5/8 NC thread specification listed for the MM52 multi-purpose tractor.
- Correct Thread Form — the National Coarse (NC) thread profile is a precise designation; using the wrong pitch or diameter risks cross-threading or inadequate clamping, making the correct part number critical.
- Serial Number Verification — Honda updates fastener specifications at production breaks, so confirm your MM52 serial number against the fitment table before ordering.
A jam nut is a thin hex nut threaded against a standard nut or along a threaded rod to lock a fastener assembly in place and prevent unwanted loosening under vibration or load. On equipment like the MM52 multi-purpose tractor, which operates under sustained mechanical stress, a properly torqued jam nut keeps the fastener stack secure. A missing or incorrectly sized jam nut allows the primary nut to back off over time, leading to looseness in the assembly it secures.
