The Honda 90365-750-881 Lock Flange Nut (7/16-14) is a genuine OEM Lock Flange Nut designed for the HT3810 lawn tractor. As a direct Honda OEM part, it matches the original specification for thread size and flange geometry, ensuring it seats correctly without modification. Confirm your machine's serial number against the fitment table before ordering to make sure this is the correct variant for your unit.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this nut matches the original thread pitch and flange diameter used on the HT3810 lawn tractor.
- Locking Flange Design — the integrated flange distributes clamping load evenly across the mating surface, while the locking feature resists loosening under vibration during mowing operation.
- 7/16-14 Thread Specification — the thread size is the key match point; verify this against your existing hardware before ordering.
- Serial Number Verification Recommended — Honda updates hardware specifications at production breaks, so cross-check your tractor's serial number against the fitment table to confirm this nut is correct for your build.
A lock flange nut combines a standard hex nut with an integral flange that acts as a built-in washer, spreading the load and resisting rotation under vibration. On a lawn tractor like the HT3810, where components are subject to continuous vibration during cutting, hardware that stays secure is essential to keeping assemblies properly torqued. A worn, stripped, or missing lock flange nut can allow fastened components to shift or work loose over time, leading to accelerated wear or the need for more involved repairs.
