The Husqvarna 539102653 Flat Washer 5/8 Plated is a genuine OEM component designed for the FS4800D, FS6600D, FS6800D, FS8400D, and PRO65G floor saws.

It installs to the correct fastener stack-up without modification, ensuring proper load distribution across the hardware assembly. DHS Equipment supplies this part to help keep your floor saw operating correctly.
Key Features
- OEM-Spec Plated Steel Construction — manufactured to Husqvarna's exact material and plating specification, providing the correct hardness and corrosion resistance for a structural fastener application in floor saw assemblies.
- Exact 5/8" Diameter Match — sized precisely to the 5/8" fastener hardware used in these machines, seating flush and distributing clamping load evenly across mating surfaces.
- Broad Floor Saw Compatibility — fits the FS4800D, FS6600D, FS6800D, FS8400D, and PRO65G floor saws, covering a wide range of Husqvarna walk-behind flat saw models.
- Structural Integrity Under Load — a correctly fitted washer prevents fastener pull-through, surface deformation, and loosening under the vibration and stress typical of concrete cutting operations.
- Verified OEM Part Number — cross-reference part number 539102653 against your machine's parts diagram to confirm the correct position before ordering.
A flat washer serves as a load-distributing interface between a fastener — such as a bolt or nut — and the surface it bears against. By spreading the clamping force over a wider area, it protects the mating surface from damage and helps the fastener maintain consistent tension, even under the vibration generated during cutting. When a washer is missing, undersized, or worn flat, the fastener can work loose over time, leading to misalignment or damage to the surrounding components.
