The Honda 90011-Z3E-901 Socket Bolt (5X10) is a genuine OEM fastener designed for FG110 tillers, GX25 horizontal shaft engines, HHT25 and UMC425 trimmers, and WX10 water pumps. As a factory-original component, this bolt is manufactured to Honda's exact dimensional specifications, ensuring a proper fit without guesswork. Honda supersedes hardware at serial breaks, so verify your unit's serial number against the fitment table before ordering. If you are replacing multiple fasteners, confirm part number 90011-Z3E-901 against your machine's parts diagram to make sure this is the correct bolt position and quantity.
Key Features
- Genuine OEM Honda Hardware — sourced directly from Honda, this socket bolt carries the exact thread pitch, head geometry, and dimensions specified for these applications, so it seats and torques correctly the first time.
- Broad Cross-Equipment Fitment — listed for FG110 tillers, GX25 engines, HHT25 and UMC425 trimmers, and WX10 water pumps, covering a range of Honda handheld, tiller, and pump equipment.
- Verify by Serial Number — Honda updates hardware specifications at production breaks, so match your machine's serial number to the fitment table to confirm this is the correct supersession for your unit.
A socket bolt is a fastener driven by an internal hex (Allen) socket rather than an external wrench flat. This drive style allows it to be installed in tighter clearances where a standard bolt head would not fit, and it distributes clamping load evenly across the joint it secures. Using the correct OEM bolt — right thread size, length, and head type — ensures the joint holds to its intended torque value; a mismatched fastener can strip threads, back out under vibration, or fail to clamp the assembly properly.
