The Honda 90011-Z0H-801 Socket Bolt (5X10) is a genuine OEM fastener designed for GX25 horizontal shaft engines and WX10 water pumps. As a direct Honda OEM part, it is manufactured to the exact dimensions and drive specifications of the original hardware. This bolt is listed for both the GX25 engine and the WX10 water pump — confirm the application against your machine's serial number and the fitment table before ordering. Keeping the correct fastener in place ensures assemblies stay properly torqued and secure during operation.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, matching the original 5 mm × 10 mm socket-drive specification exactly as engineered for these applications
- Dual-Application Listing — part number 90011-Z0H-801 is listed for GX25 horizontal shaft engines and WX10 water pumps; verify your specific machine and serial number against the fitment table to confirm the correct fit
- Serial Number Awareness — Honda supersedes fasteners at production breaks, so checking your machine's serial number against the compatibility table is the surest way to confirm this is the right bolt for your unit
A socket bolt is a threaded fastener driven by an internal hex (Allen) socket rather than an external hex head. The 5 mm diameter and 10 mm thread length of this bolt place it in the small-displacement hardware common to compact Honda engines and lightweight pump equipment. When a fastener of this type is missing, stripped, or under-torqued, the assembly it secures can work loose during operation, leading to vibration, misalignment, or component damage — replacing it with the correct OEM piece restores the original clamping integrity.
