Key Features
- Genuine OEM Honda Part — sourced directly from Honda's parts catalog, ensuring the correct thread specification and locking function for the H6522
- Exact Replacement Hardware — the 78MM size designation identifies this specific variant; confirm this matches the application on your machine before ordering
- Serial Number Verification Recommended — Honda supersedes hardware at production breaks, so cross-check your H6522 serial number against the fitment table to confirm this is the correct listing for your unit
A lock nut is a fastener engineered to resist loosening under vibration and dynamic loads. Unlike a standard nut, its locking feature — whether a nylon insert, a distorted thread profile, or a prevailing-torque design — keeps the joint secure even as the machine cycles through normal operation. On equipment like the H6522 compact tractor, where vibration from the drivetrain and working attachments is constant, using the correctly sized and specified lock nut matters: an undersized or non-locking substitute can back off over time, allowing the joint to work loose and potentially damage surrounding components.
