The Honda 90042-ZA0-950 Stud Bolt (8X135) is a genuine OEM fastener designed for EX5500 generators and GX360 horizontal shaft engines. As a direct Honda OEM component, this stud bolt is manufactured to the same specification as the original hardware it replaces. Honda supersedes fastener part numbers at production serial breaks, so confirm part number 90042-ZA0-950 against your machine's serial number before ordering. This stud bolt ships as a single unit — order the quantity your application requires.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, matching the original specification for thread form, shank length, and dimensional tolerances of the 8X135 stud.
- Dual-Machine Fitment — listed for EX5500 generators and GX360 horizontal shaft engines; verify your serial number against the fitment table to confirm this is the correct listing for your unit.
- Direct Drop-In Replacement — replaces the worn or damaged original stud without rework, keeping assembly straightforward on a familiar fastener layout.
A stud bolt is a headless fastener threaded at both ends: one end anchors into a tapped bore in the engine or generator housing, and the other end accepts a nut to clamp a mating component in place. Unlike a conventional bolt, a stud remains fixed in the casting, allowing mating parts to be removed and reinstalled repeatedly without disturbing the base threads. When a stud stretches, corrodes, or strips, clamping force is lost and the joint can work loose under vibration or thermal cycling — making timely replacement important for maintaining a secure assembly.
