Key Features
- Genuine Honda OEM — sourced directly from Honda, this fastener matches the original specification called out for EV4000, EV4010, EV6010, EVD4010, and EW171 units.
- Combined Screw and Washer — the integrated washer flange distributes clamping load evenly, eliminating the need for a loose separate washer during reassembly.
- Verify Before Ordering — Honda supersedes fasteners at serial number breaks; check your machine's serial number against the fitment table to confirm this is the correct listing for your unit.
A screw washer is a fastener with a washer flange formed as one piece with the screw shank. The integrated flange spreads the clamping force across a wider bearing surface than a plain screw alone, helping panels, covers, and components seat securely without distorting softer materials. Using the correct OEM fastener — matched by thread size, pitch, and length to the original — ensures proper torque retention and avoids the stripped threads or loose panels that a mismatched substitute can cause over time.
