The Honda 94011-12000-0S Castle Nut (12MM) is a genuine OEM fastener designed for Honda H3011 and H3013 riding mowers and HS55, HS70, and HS80 two-stage snow blowers. As a direct Honda OEM part, it matches the original hardware specifications exactly, so it installs without any adjustment or sourcing guesswork. Confirm your machine's serial number against the fitment table before ordering, as Honda updates hardware at production breaks and part number 94011-12000-0S applies to specific serial ranges.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, so thread pitch, slot depth, and dimensional tolerances match the original nut exactly.
- Slotted Castle Design — the castellated crown accepts a cotter pin or safety wire to prevent the nut from backing off under vibration and load cycles.
- Broad Fitment — listed for H3011 and H3013 riding mowers and HS55, HS70, and HS80 two-stage snow blowers; verify your serial number against the fitment table to confirm the correct application.
A castle nut is a threaded fastener with a series of slots cut across its top face, forming the characteristic crown shape. Those slots allow a cotter pin or safety wire to be passed through a matching hole in the bolt or shaft, locking the nut in position and preventing it from loosening during operation. This locking function is especially important on rotating or high-vibration assemblies, where an unsecured nut can work loose over time. Replacing a worn, damaged, or missing castle nut with the correct Honda OEM part restores the mechanical lock and keeps the assembly properly retained.
