Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt-washer meets the same dimensional and load requirements as the original hardware installed at the factory
- Integrated Washer Design — the captive washer distributes clamping load evenly, eliminating the need for a separate washer and ensuring consistent seating every time
- Outboard Motor Fitment — listed for BF115, BF135, BF140, and BF150 Honda outboard motors; confirm your serial number against the fitment table before ordering
- Exact Replacement — retains the original thread pitch, shank length, and flange diameter so this part installs directly in place of the worn or damaged hardware
A bolt-washer is a single-piece fastener that combines a hex bolt with a permanently attached flange washer. In an outboard motor, fasteners like this are used to secure assemblies exposed to vibration, water, and the stresses of marine operation. When a bolt-washer stretches, strips, or corrodes, the joint it holds can work loose, leading to misalignment or component damage — replacing it with the correct OEM hardware restores proper clamping force and keeps the assembly secure.
