The Honda 90104-VH8-641 Bolt-Washer (5X25) is a genuine OEM fastener designed for HHT25, HHT31, and HHT35 trimmers. As a direct Honda OEM component, this bolt-washer is manufactured to the exact dimensions specified for these trimmers, ensuring correct installation without the guesswork of sourcing a generic substitute. Honda supersedes parts at serial breaks, so confirm your trimmer's serial number against the fitment table before ordering to make sure part number 90104-VH8-641 is the correct listing for your unit.
Key Features
- Genuine OEM Fastener — sourced directly from Honda, this bolt-washer carries the correct thread specification and integrated washer geometry for the HHT series trimmer.
- Exact Dimensional Match — the 5X25 designation identifies the specific shank diameter and length; using the correctly sized fastener prevents under- or over-torquing at the mounting point.
- Broad HHT Trimmer Coverage — listed for the HHT25, HHT31, and HHT35 trimmers, including multiple serial ranges within each model.
- Serial Number Verification Recommended — Honda updates part listings at production breaks; check your trimmer's serial number against the compatibility table to confirm this is the right listing for your machine.
A bolt-washer is a single fastener that combines a threaded bolt shank with an integrated washer flange, distributing clamping load across a wider surface area than a plain bolt alone. This design helps maintain consistent clamping force and reduces the risk of surface damage or loosening under vibration — a factor relevant to handheld power equipment like string trimmers that generate continual vibration during operation. When a fastener of the wrong size or type is used as a substitute, the clamping load is distributed incorrectly, which can lead to components working loose during use.
