The Honda 92900-08040-0B is a genuine OEM Stud Bolt (8X40) designed for BF350 outboard motors, FR500 tillers, and WB20 and WB30 water pumps. As a direct Honda OEM component, this stud bolt is manufactured to Honda's exact dimensional specifications, ensuring a proper fit across each listed application. Honda parts are superseded at production breaks, so confirm part number 92900-08040-0B against your machine's serial number in the fitment table before ordering. This stud bolt is a straightforward, no-substitution replacement that keeps your equipment running with the hardware Honda specified at the factory.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this stud bolt carries the exact thread pitch, shank length, and diameter Honda specifies for each listed application, so you are not guessing on a close-enough substitute
- Broad OEM Coverage — listed for BF350 outboard motors, FR500 tillers, and WB20 and WB30 water pumps, making it a stocked fastener across multiple Honda product lines
- Verify by Serial Number — Honda updates hardware specifications at production breaks; check your machine's serial number against the compatibility table to confirm this is the correct bolt for your unit
- Structural Integrity — a correctly fitted stud bolt holds clamping load consistently; a worn, stripped, or incorrect-length stud compromises the joint it secures and can lead to loosening under vibration and load
A stud bolt is a fully threaded or partially threaded fastener with no head — it threads into a fixed component on one end and accepts a nut on the other, creating a secure, repeatable clamping joint that can be assembled and disassembled without disturbing the threaded bore. The 8X40 designation identifies the nominal thread diameter and shank length of this stud. On Honda water pumps, tillers, and outboard motors, stud bolts are used where a conventional bolt cannot be driven from the outside of an assembly or where precise clamping depth is required. When a stud bolt stretches, strips, or corrodes, it can no longer hold the joint to spec, leading to leaks, looseness, or component damage on the equipment it belongs to.
