Key Features
- Genuine OEM Material Spec — manufactured to Husqvarna's exact thickness and hardness tolerances, ensuring consistent load distribution across fastened assemblies on heavy-duty floor saws.
- Direct Drop-In Replacement — matches the original mounting configuration so this washer seats correctly without rework or modification to surrounding hardware.
- Broad FS-Series Compatibility — fits the FS4800, FS5000, FS6600, FS6800, FS7000, FS8400, and FS9900 walk-behind floor saws in a single OEM part number.
- Protects Fastener Integrity — a correctly sized washer prevents fastener pull-through and surface damage under the high vibration loads common to concrete cutting equipment.
- Verified OEM Part Number — ordering by part number this part ensures you receive the exact component Husqvarna specifies, eliminating guesswork during reassembly.
A washer distributes the clamping load of a bolt or nut across a wider surface area, preventing the fastener from digging into or pulling through the mating component. On walk-behind floor saws like the FS4800 through FS9900, which operate under continuous vibration and significant cutting forces, correctly spec'd washers are critical to maintaining tight, secure assemblies throughout the machine. When a washer is damaged, deformed, or missing, fasteners can loosen progressively, leading to component movement, accelerated wear on adjacent parts, and potential structural failure at the connection point.
