Key Features
- Genuine OEM Hardware — sourced directly from Honda, this bolt-washer meets the exact dimensional and clamping specifications called out in Honda's own parts diagrams
- Integrated Washer Design — the captive washer distributes clamping load evenly across the mating surface, maintaining consistent fastening without a separate loose washer
- Broad Fitment — listed for GX22 and GX31 horizontal shaft engines and UMK422 and UMK431 trimmers; verify your serial number against the fitment table to confirm the correct application
A bolt-washer is a fastener that combines a bolt and an integral washer into a single piece, eliminating the need for a separate washer and ensuring the load-bearing surface is always correctly positioned. The integrated washer spreads clamping force over a wider area than a bare bolt head alone, helping to prevent loosening from vibration during operation. When a bolt-washer is missing, stripped, or replaced with a non-matching fastener, clamping force drops unevenly and the retained component can work loose during use.
