The Honda 90103-VK4-003 Socket Bolt (5X20) is a genuine OEM fastener designed for the GX35 horizontal shaft engine. Sourced directly from Honda, this bolt matches the original specification for its position in the GX35, ensuring correct torque and secure retention without improvised substitutes. Always confirm your engine's serial number against the fitment table before ordering, as Honda updates part numbers at specific serial breaks.
Key Features
- Genuine Honda OEM — an authentic Honda replacement carrying the exact dimensions and thread specification as the original bolt supplied on the GX35 production line.
- Correct Socket Drive Profile — the socket-head drive format allows proper torquing in tight spaces typical of the compact GX35 engine package.
- GX35 Fitment — listed for GX35 horizontal shaft engines; confirm your serial number against the compatibility table to ensure this is the correct part for your serial range.
A socket bolt is a hex-socket cap screw that uses an internal Allen-type drive, allowing precise tightening in confined areas where a standard hex-head wrench may not have room to turn. In a compact engine like the GX35, correctly fastened bolts maintain component alignment and clamping load throughout normal operation. A bolt that is the wrong size, pitch, or drive type can back out over time or fail to seat properly, leading to loosened components and potential engine damage.
