The Honda 90042-ZB7-000 Stud Bolt (8X111) is a genuine OEM fastener designed for GX270 and GX340 horizontal shaft engines, EX3300 and EX4500 generators, and the EXW171 welder generator. As a direct Honda OEM part, it meets the same specifications as the original hardware installed at the factory. Verify your model and serial number against the fitment table before ordering, as Honda updates stud bolt specifications at serial number breaks.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this stud bolt matches the original specification for correct thread engagement and clamping load across every application it covers
- Broad Cross-Platform Fitment — listed for GX270 and GX340 horizontal shaft engines as well as EX3300 and EX4500 generators and the EXW171 welder generator, making it a single part number across multiple Honda product lines
- Serial Number Verification Recommended — Honda supersedes fastener part numbers at production breaks, so confirm your unit's serial number against the fitment table to ensure this is the correct stud for your machine
- Exact Dimensions Matter — the (8X111) designation identifies this stud's thread diameter and length; installing a stud of the wrong length can result in incorrect fastener engagement, so match this specification to your application
A stud bolt is a headless threaded fastener that is permanently threaded into a casting or housing on one end, with the opposing end left exposed to accept a nut. This design is common in engine and equipment assemblies where a component must be removed repeatedly for service — the stud stays in place while the mating part slides on and off. A stud that is stripped, corroded, or broken prevents proper clamping of the mating component, which can lead to leaks, misalignment, or component failure during operation.
