The Honda 94012-14080-0S Castle Nut (14MM) is a genuine OEM fastener designed for H4013, H4514, and H4518 lawn tractors. As a direct Honda OEM component, this castle nut is manufactured to the exact dimensions Honda specifies for these machines. Verify your tractor's serial number against the fitment table to confirm part number 94012-14080-0S is correct for your unit before ordering.
Key Features
- Genuine Honda OEM Construction — sourced directly from Honda, this castle nut matches the exact thread pitch, hex size, and slot geometry Honda engineers specified for the H4013, H4514, and H4518 lawn tractors.
- Correct 14MM Sizing — the (14MM) designation identifies this as a specific variant; confirm your application calls for the 14MM size before installing.
- Cotter Pin Retention — the castle profile accepts a cotter pin through the shaft to lock the nut against rotation, maintaining the clamp load Honda's design requires.
- Serial Number Verification Recommended — Honda updates fastener specifications across production runs, so check your tractor's serial number against the compatibility table to ensure this is the right nut for your machine.
A castle nut is a hex nut with a series of slots cut into one end, resembling the battlements of a castle. Those slots allow a cotter pin or safety wire to pass through a drilled hole in the mating shaft, locking the nut in place and preventing it from loosening under vibration or load. On lawn tractors like the H4013, H4514, and H4518, castle nuts are used in locations where maintaining a precise clamping force — and ensuring the nut cannot back off — is essential to proper operation. A missing or damaged castle nut, or one installed without the corresponding cotter pin, allows the joint to loosen over time, leading to excessive play and potential loss of control of the affected assembly.
