The Honda 93893-05008-07 Screw Washer (5X8) is a genuine OEM component designed for GX630, GX660, and GX690 horizontal shaft engines. As a factory-sourced part, this screw washer carries Honda's exact dimensional specifications, ensuring it seats and functions exactly as the original did. Buyers should confirm their engine's serial number against the fitment table to make sure part number 93893-05008-07 corresponds to their specific production run.
Key Features
- Genuine OEM Sourcing — manufactured to Honda's own specifications, so the thread pitch, washer diameter, and head geometry match what came off the assembly line.
- Direct Replacement — installs in place of the original without modification, maintaining the correct clamping interface for GX630, GX660, and GX690 engines.
- Serial Number Verification Recommended — Honda supersedes hardware at production breaks, so cross-check your engine's serial number against the fitment table before ordering.
A screw washer is a combined fastener that integrates a captive washer with a machine screw, distributing clamping load across a broader surface area than a plain screw alone. This helps prevent the fastener from pulling through or distorting softer cover and housing materials over repeated service cycles. When the original screw washer is lost, damaged, or stripped, replacing it with the correct OEM part restores proper clamping force and keeps the assembled joint secure through normal engine operation.
