Key Features
- Genuine OEM Specification — sourced directly from Husqvarna, this nut is manufactured to the exact thread pitch, diameter, and material grade required for correct fastener engagement in the assembly
- Direct Assembly Fit — engineered to install without rework or modification, matching the original fastener position and torque requirements of the host component
- Compatible with FS400LV and FS600E Floor Saws — confirmed fitment for both walk-behind floor saw models, keeping your machine correctly assembled and structurally sound
- Structural Integrity Restored — a correctly fitted nut maintains proper clamping force across connected components; a worn, stripped, or missing fastener can compromise alignment and lead to premature wear on surrounding parts
A nut is a threaded fastener that works in conjunction with a bolt or stud to clamp and secure components within an assembly. In a walk-behind floor saw like the FS400LV or FS600E, fasteners play a critical role in holding structural, drive, and blade-guard components in precise alignment under the significant vibration loads generated during cutting. When a nut becomes stripped, corroded, or damaged, it can no longer maintain proper clamping force — leading to loosening of connected parts and potential misalignment or component damage. Replacing it with the correct OEM part restores the integrity of the fastened joint and keeps the saw operating as designed.
