Key Features
- Genuine Honda OEM Hardware — sourced directly from Honda, this screw-washer matches the original fastener in thread pitch, head diameter, and washer dimensions for a true like-for-like swap.
- Integrated Washer Design — the captive washer distributes clamping load evenly across the mating surface, reducing the risk of the fastener working loose under vibration.
- Broad Fitment Coverage — listed for Honda generators, vertical shaft engines including GXV610, GXV620, and GXV670, tillers, lawn mowers, and compact tractors; check your serial number against the fitment table to confirm applicability.
- Exact Replacement — replaces part number 93891-05012-08 directly, with no rework or adaptation needed at the installation point.
A screw-washer is a fastener that combines a threaded screw with a permanently attached washer in a single piece. The washer bearing surface spreads the tightening force over a wider area than a plain screw head alone, helping secure panels, covers, and components against loosening from engine or equipment vibration. When the original fastener is stripped, corroded, or lost, replacing it with the correct Honda OEM screw-washer restores proper clamping force and keeps the assembly held together as intended.
