Key Features
- OEM-Grade Fastener Specification — Manufactured to the 10.9 strength grade, delivering the high-tensile clamping force required for structural and mechanical assemblies on Husqvarna wall saws and wire saws.
- Fzb Zinc-Flake Coating — The factory-specified fzb (zinc-flake) surface finish provides corrosion resistance suited to the demanding wet-cutting and outdoor environments these machines operate in.
- Exact OEM Dimensions — The MF6S 8x12 geometry matches the original hardware precisely, allowing this screw to seat and torque correctly without modification to mating components.
- Broad Wall Saw and Wire Saw Compatibility — Fits the WS220, WS400, WS440, WS440HF, WS460, WS462, WS463, WS482, WS482HF, WS8 wall saws and the CS10 wire saw — cross-reference part number 725644751 against your parts diagram to confirm the correct assembly position.
- Structural Integrity Restored — Using the correct grade fastener ensures clamping loads are maintained as designed; an incorrect or under-spec substitute can lead to fastener failure, loosening under vibration, or damage to mating parts.
This screw is a high-strength structural fastener used throughout the assemblies of Husqvarna wall saws and wire saws to secure components under significant mechanical load and vibration. The 10.9 strength grade designation means it is engineered to withstand higher clamping and tensile forces than standard hardware-grade fasteners, making it appropriate for the demanding cutting cycles these machines perform. When a fastener of this type is missing, damaged, or replaced with an incorrect grade, it can compromise the integrity of the assembly it secures, leading to loosening, component misalignment, or accelerated wear on surrounding parts.
