The Honda 90010-Z3V-003 Socket Bolt (5X39) is a genuine OEM fastener designed for the GX50 horizontal shaft engine. As a direct Honda OEM part, it is manufactured to the exact dimensions and thread specification Honda calls for in the GX50, ensuring it installs correctly without modification. If you are servicing a GX50 engine and need to replace this hardware, confirm your engine's serial number against the fitment table to ensure part number 90010-Z3V-003 applies to your unit.
Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this socket bolt meets the exact dimensional and thread requirements specified for the GX50 engine, so it seats and clamps correctly every time
- Exact-Fit Replacement — built to Honda's own dimensions for the GX50 horizontal shaft engine, this bolt installs as a direct replacement with no rework needed
- Serial Number Verification Recommended — Honda supersedes fasteners at production breaks, so check your GX50 engine serial number against the fitment table before ordering to confirm this is the correct bolt for your unit
A socket bolt is a cap-head fastener driven by a hex key rather than a conventional wrench, allowing it to be seated in tighter spaces than a standard hex-head bolt. In the GX50 engine, this type of fastener is used where controlled clamping torque and a flush or recessed head profile are required. Using the correctly sized OEM bolt — in this case the 5 mm diameter, 39 mm length specification of part number 90010-Z3V-003 — ensures the joint holds to Honda's design intent and prevents stripped threads or undertorqued connections that can lead to component loosening in service.
