The Honda 94012-12280-0S Castle Nut (12MM) is a genuine OEM fastener designed for the H6522 compact tractor. As a direct Honda OEM part, it is produced to the same specifications as the original hardware installed at the factory. If you are sourcing a replacement for your H6522, confirming the part number 94012-12280-0S against your machine's parts diagram is the surest way to verify the correct fitment before ordering.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this castle nut matches the original specification for the H6522 compact tractor, so it seats and torques correctly without adjustment.
- 12MM Castle Nut Profile — the castellated crown is designed to accept a cotter pin or safety wire, locking the nut securely in position under load and preventing loosening through vibration.
- Serial Number Verification Recommended — Honda updates hardware specifications at production breaks, so cross-checking your tractor's serial number against the fitment table before ordering ensures you receive the right nut for your unit.
A castle nut is a hex nut with a series of slots cut into one end, forming a crown that resembles the battlements of a castle. Once torqued to specification, a cotter pin or safety wire is passed through those slots and a corresponding hole in the bolt or shaft, preventing the nut from rotating and backing off under the vibration and load that a compact tractor like the H6522 generates during operation. When a castle nut is worn, cross-threaded, or missing its cotter pin, the assembly it secures can work loose, affecting machine performance and requiring more extensive repairs to correct.
