The Honda 90018-ZK6-P10 Stud Bolt (8X22) is a genuine OEM fastener designed for GX240, GX270, GX340, and GX390 horizontal shaft engines. As a direct Honda OEM component, this stud bolt is sourced and manufactured to the same specifications as the original hardware installed at the factory.

Key Features
- Genuine OEM Hardware — sourced directly from Honda, ensuring this stud bolt matches the thread pitch, shank diameter.
- Exact-Dimension Fit — the 8X22 sizing means this bolt installs directly without modification, maintaining correct clamping engagement in the engine assembly
- Broad GX-Series Compatibility — listed for GX240, GX270, GX340, and GX390 horizontal shaft engines, covering Honda's most widely used commercial engine range
- Serial-Range Awareness — Honda updates fastener part numbers at production breaks; always cross-reference your engine's serial number with the fitment table to confirm this is the correct stud bolt for your unit
A stud bolt is a headless fastener threaded on both ends, designed to be permanently anchored into one component while a nut is torqued down onto the exposed end to clamp a second component in place. This design allows repeated assembly and disassembly — such as during routine service — without disturbing the base thread. Using a correctly sized OEM stud bolt matters because an undersized or incorrect-pitch fastener will not achieve proper clamping force, which can lead to loosening, leaks, or component damage over time.
