Key Features
- Genuine OEM Material Grade — Manufactured to Husqvarna's original hardness and thread specification, delivering the clamping force and shear resistance the assembly was engineered around.
- Direct Drop-In Replacement — Matches the original thread pitch, head type, and length so it installs into the existing hole pattern without rework or modification.
- Broad Saw Family Coverage — Fits the FS6600D, FS6800D, and FS8400D floor saws and the MS510, MS510G, and MS610 tile and masonry saws, making it a versatile fastener across Husqvarna's cutting equipment lineup.
- Structural Integrity Restored — A correctly torqued OEM screw keeps covers, guards, and structural panels firmly located, preventing vibration-induced loosening during demanding cutting operations.
- Guard and Panel Security — On floor saws and masonry saws, fasteners that secure guards and housings are safety-critical; using the correct OEM part maintains the intended level of protection for the operator.
A screw may appear to be a minor component, but in floor saw and masonry saw assemblies it plays a direct role in holding covers, panels, guards, and internal brackets in their engineered positions. When a screw is stripped, sheared, or missing, the surrounding assembly can shift under vibration, accelerating wear on adjacent components and potentially exposing moving parts. Replacing a damaged or missing fastener with the correct OEM unit restores the mechanical integrity of the assembly and ensures the machine performs as designed.
