The Honda 93892-05010-07 Screw Washer (5X10) is a genuine OEM fastener designed for GX35 horizontal shaft engines, UMK422 trimmers, and UMK431 trimmers. As a direct Honda OEM component, this screw washer is sourced to the exact specification used in original assembly, ensuring the hardware matches what was installed at the factory. Confirm your machine's serial number against the fitment table before ordering, as Honda periodically supersedes hardware at production breaks.
Key Features
- Genuine OEM Hardware — sourced directly from Honda, this screw washer matches the original fastener specification used in assembly of GX35 engines and UMK422 and UMK431 trimmers
- Integrated Washer Design — the combined screw-and-washer format provides consistent clamping and eliminates the need to source a separate washer, keeping the assembly correct
- Broad Fitment — listed for GX35 horizontal shaft engines, UMK422 trimmers, and UMK431 trimmers; verify your serial number against the compatibility table to confirm the correct application
- Exact Sizing — the 5X10 designation identifies the thread diameter and length, so buyers can match part number 93892-05010-07 to the specific fastener location on their machine
A screw washer is a combined fastener that integrates a captive washer into a single screw, distributing clamping load evenly across the mating surface while securing a panel, cover, or bracket in place. This design prevents the washer from being lost during disassembly and ensures correct load distribution every time the fastener is torqued down. Using the correct OEM screw washer matters because a mismatched fastener — wrong thread pitch, wrong diameter, or wrong length — can strip threads, fail to clamp properly, or allow a cover or component to work loose during operation.
