Key Features
- Genuine OEM Honda Fastener — sourced directly from Honda, ensuring the correct thread pitch, head diameter, and washer bearing surface for these specific applications
- Broad Compatibility — listed for GX240, GX270, GX340, and GX390 horizontal shaft engines, and EL5000 and ES6500 generators; verify your serial number against the fitment table to confirm the correct part for your unit
- Exact Replacement — a combined screw-and-washer design that installs as a single piece, eliminating the need to source a separate fastener and washer
A screw washer is a fastener that integrates a captive washer with the screw shank, distributing clamping load across a wider surface area than a plain screw alone. This helps secure panels, covers, or components evenly without concentrating stress at a single contact point. Using the correct OEM screw washer — with the right thread size, length, and washer diameter — ensures components seat properly and stay secured under the vibration and heat cycling these engines and generators produce in normal operation.
