Key Features
- Genuine OEM Thread Specification — Manufactured to Husqvarna's exact 3/8-16 thread pitch and 3/4-inch length, ensuring consistent torque load and proper clamping force across the assembly.
- Direct Hardware Replacement — Engineered to seat and thread exactly as the original, with no reworking of mounting points or hardware required.
- Broad Floor Saw Compatibility — Fits FS4600G, FS6600D, FS8400D, and RS8500D floor saws, covering a range of Husqvarna's walk-behind slab saw lineup.
- Structural Integrity Restored — A correct-spec fastener maintains the clamping force and alignment critical to safe, stable floor saw operation; an incorrect or worn bolt can compromise the integrity of the assembly it secures.
A fastener of this specification serves as a structural connector within the floor saw assembly, holding components firmly in place under the vibration and load demands of concrete cutting. Using the correct thread pitch and grip length matters — an undersized or mismatched bolt can back out under vibration or fail to achieve the clamping force the joint requires, leading to component movement and accelerated wear. Replacing a damaged or missing fastener with the correct Husqvarna OEM bolt restores the assembly to its designed structural condition.
