The Honda 90201-Z0H-J00 Special Nut (4mm) is a genuine OEM fastener designed for GX25 horizontal shaft engines, HHT25 trimmers, HS1336 two-stage snow blowers, and HSM1336 two-stage snow blowers. As an authentic Honda OEM part, it is manufactured to the exact dimensions and specifications Honda requires for these applications. This nut is a direct, like-for-like replacement — match part number 90201-Z0H-J00 to your machine's parts diagram to confirm the correct position before ordering.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, meaning the thread form, head geometry, and dimensional tolerances are exactly what Honda specifies for these assemblies
- Broad Equipment Coverage — listed for GX25 horizontal shaft engines, HHT25 trimmers, HS1336 two-stage snow blowers, and HSM1336 two-stage snow blowers
- Verify by Serial Number — Honda supersedes hardware at production breaks, so check your machine's serial number against the fitment table to confirm this is the correct nut for your unit
- Exact Replacement — the 4mm special profile makes this a specific fastener rather than a standard nut; using the correct part ensures proper clamping and assembly integrity
A special nut differs from a standard hex nut in that its profile, thread engagement, or seating geometry has been engineered to suit a specific assembly point. Using the correct special nut ensures the fastener seats and clamps as Honda intended. Substituting a generic nut in its place risks improper seating, insufficient clamping force, or damage to the mating component — any of which can compromise the assembly over time.
