Key Features
- Genuine OEM Hardware — sourced directly from Honda, this screw washer matches the original fastener your generator shipped with, so there is no guesswork on sizing or thread specification
- Correct 5 x 20 Dimensions — the (5X20) designation identifies the specific size variant; verify this matches the fastener called out in your generator's parts diagram before ordering
- Broad Generator Fitment — listed for E3500, E4500, ES3500, and ES4500 Honda generators; check your serial number against the fitment table to confirm the correct part for your unit
- Direct Drop-In Replacement — replaces a worn, stripped, or missing original screw washer and restores the assembly to its original condition
A screw washer is a combination fastener that integrates a washer flange into the screw head, distributing clamping load across a broader surface area than a standard screw alone. On Honda generators, these fasteners secure panels, covers, and assemblies where consistent clamping force and surface protection matter. When a screw washer is stripped or missing, the component it secures can loosen over time, leading to vibration-related wear or an improperly seated cover.
