The Honda 90201-MY5-730 Lock Nut is a genuine OEM component designed for the HRS216 lawn mower. As a direct Honda OEM part, it is manufactured to the same specifications as the original hardware installed at the factory. Buyers should confirm their serial number against the fitment table, as Honda updates part numbers at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this lock nut matches the original specification for the HRS216 lawn mower.
- Exact Replacement Hardware — designed to install directly in place of the original, with no modification needed to the surrounding components.
- Serial Number Verification Recommended — Honda supersedes hardware at production breaks, so checking your machine's serial number against the fitment table ensures you receive the correct part for your unit.
A lock nut is a fastener engineered to resist loosening under vibration and repeated loading. Unlike a standard nut, its locking feature — whether a nylon insert, a prevailing-torque profile, or a deformed thread section — maintains clamping force even as the surrounding components flex and vibrate during operation. On a walk-behind lawn mower like the HRS216, where vibration from the cutting blade and engine is continuous, a properly functioning lock nut keeps critical assemblies securely in place. A worn or missing lock nut can allow fastener joints to back off, leading to loose components and eventual mechanical failure.
