Key Features
- Genuine OEM Hardware Grade — manufactured to Husqvarna's exact material and thread specification, ensuring the correct torque retention and clamping force for the application
- Direct Drop-In Replacement — matches the original thread pitch, diameter, and seat profile for a clean installation without rework or modification
- Confirmed Fitment — compatible with the FS400LV and FS600E walk-behind floor saws, covering both models in this flat saw range
- Structural Integrity Restored — a properly torqued fastener keeps critical assemblies secure during high-vibration cutting operations; a worn or damaged nut risks loosening and assembly failure mid-cut
A nut is a threaded fastener that works in combination with a bolt or stud to clamp and secure machine components in place. In a walk-behind floor saw like the FS400LV and FS600E, fasteners throughout the drive train, blade guard, and frame assemblies are subject to continuous vibration and mechanical stress during operation. When a nut becomes stripped, cross-threaded, or corroded, it can no longer maintain the clamping load needed to hold the assembly together, which can lead to component movement, misalignment, or equipment damage. Replacing it with the correct OEM part restores the assembly to its designed specification.
