The Honda 90311-772-701 Hexagon Lock Nut (5/16-24) is a genuine OEM component designed for the H1011 riding mower. As a direct Honda OEM part, it is manufactured to the exact specifications Honda established for this application, ensuring the correct thread pitch and locking characteristics. Confirm your unit's serial number against the fitment table before ordering to make sure part number 90311-772-701 is the right match for your machine.
Key Features
- Genuine OEM Fit — sourced directly from Honda, this nut matches the exact thread specification (5/16-24 UNF) called out for the H1011 riding mower
- Locking Design — the lock nut format resists loosening under the vibration and load cycles that riding mower operation generates, maintaining the integrity of the fastened joint
- Serial Number Verification — Honda updates parts at production breaks, so always cross-check your H1011's serial number against the fitment table to confirm this is the correct nut for your build
A hexagon lock nut is a standard fastener with an integrated locking feature — typically a nylon insert or a distorted thread section — that prevents it from backing off under vibration or repeated stress cycles. On a riding mower like the H1011, fasteners like this one are used throughout the machine to keep assemblies secured during operation over uneven terrain. When a lock nut loses its locking ability or is replaced with a standard nut of the wrong thread specification, the joint it secures can work loose over time, leading to unwanted movement or wear at that connection point. Using the correct Honda OEM replacement ensures the thread engagement and retention characteristics match what was specified for the original assembly.
