Key Features
- Genuine OEM Hardware — manufactured to Husqvarna's exact thread pitch, dimensional tolerancing, and material grade for this specific fastener application, ensuring correct clamping load and mechanical integrity.
- Direct Drop-In Replacement — engineered to seat and torque identically to the original, with no rework or modification to mating components required.
- Confirmed Floor Saw Fitment — cross-reference part number 543044757 against your parts diagram to confirm the correct position on the FS400LV and FS600E floor saws.
- Structural Holding Power — a correctly fitted nut maintains the secure assembly of critical components; a worn, stripped, or incorrect replacement risks loosening under the vibration loads typical of concrete cutting operations.
- OEM Part Number Traceability — ordering by Husqvarna part number 543044757 eliminates guesswork and ensures you receive the exact hardware specified for these machines.
A nut is a fundamental fastener that works in conjunction with a bolt or threaded stud to clamp and secure machine components in place. On a walk-behind floor saw like the FS400LV and FS600E, fasteners are subjected to continuous vibration and mechanical stress during cutting operations, making correct specification critical. Using an improperly sized or lower-grade replacement can lead to fastener loosening, component misalignment, or premature hardware failure — all of which interrupt cutting operations and can cause further damage to surrounding assemblies.
