Key Features
- OEM-Specified Grade 10.9 Fastener — manufactured to the high-tensile 10.9 property class called out in Husqvarna's original design, delivering the clamping force and shear resistance the assembly requires
- Exact Thread Form and Length — the K6S 10x40 designation confirms the thread profile, diameter, and shank length match the original hardware precisely, so the screw installs cleanly into existing threaded bores
- Compatible with WS460 and FS700E Equipment — fits the WS460 wall saw and FS700E floor saw, two demanding professional cutting platforms where fastener integrity directly affects structural stability
- Fzb Finish for Corrosion Resistance — the zinc-flake fzb surface treatment resists the moisture, slurry, and debris exposure common in concrete cutting environments, helping the fastener maintain its holding strength over time
- Genuine Husqvarna OEM Part — produced to Husqvarna's construction-equipment specifications, ensuring dimensional and material consistency with every other component in the assembly
A structural fastener like this screw is responsible for maintaining the mechanical connection between major components of the saw assembly. In high-vibration cutting applications — such as wall sawing and floor sawing through reinforced concrete — fasteners are subjected to sustained dynamic loads that can cause undertorqued or incorrect-grade hardware to loosen or fail prematurely. Using the correctly specified fastener preserves joint integrity, keeps critical assemblies aligned, and prevents accelerated wear on the components it secures.
