The Multiquip 0040506000 is a genuine OEM Toothed Washer Denyo designed for GAW135H and GAC2.2HZ series equipment. As a factory-sourced component, it meets the exact specifications set by Multiquip for use in these gasoline-powered welder and generator applications. This washer is a direct-fit replacement that restores proper fastener clamping and electrical bonding integrity to your machine. Confirm your model code against the fitment data before ordering to ensure a correct match.
Key Features
- Genuine OEM Construction — Sourced directly from Multiquip, this toothed washer meets the exact material hardness and tooth geometry required for secure fastener engagement in Denyo-built components.
- Direct-Fit Replacement — Engineered to the same dimensional profile as the original, this washer seats correctly without rework or shimming during reassembly.
- Confirmed Fitment — Compatible with GAW135H gasoline arc welder and GAC2.2HZ gasoline-powered generator models.
- Secure Clamping and Locking Performance — The serrated tooth profile bites into mating surfaces under torque load, resisting loosening caused by vibration during generator or welder operation.
- Electrical Grounding Integrity — In electrical assemblies, toothed washers provide low-resistance metal-to-metal contact — using the correct OEM specification washer helps maintain proper ground continuity in the circuit.
A toothed washer, sometimes called a serrated or star washer, is a hardened fastener component with notched teeth along its inner or outer edge. When a bolt or nut is tightened against it, the teeth bite into the surrounding metal surfaces and resist rotational loosening — a critical function in equipment that generates continuous vibration, such as generators and welders. In electrical assemblies, the toothed profile also cuts through surface oxidation to maintain a reliable ground connection. A missing or worn toothed washer can allow fasteners to back out over time or introduce resistance into grounded circuits, both of which can lead to operational faults or component damage.
