Key Features
- Grade 5 Fastener Strength — Manufactured to Grade 5 tensile specifications, delivering the clamping force and shear resistance required for structural assembly points on walk-behind floor saws.
- Exact Thread and Dimension Match — 1/4-20 thread form and 2-inch length match the original Husqvarna specification, seating correctly without re-tapping or shimming.
- Genuine OEM Sourcing — Produced to Husqvarna's own part standards, ensuring the correct material grade and torque characteristics are maintained across the assembly.
- Broad Floor Saw Fitment — Compatible with the Pro65G, RS8500D, and FS4600G floor saws, covering multiple models in Husqvarna's walk-behind flat saw lineup.
- Maintains Assembly Integrity — Using the correctly specified fastener prevents joint loosening, component misalignment, and wear on mating surfaces over the machine's service life.
A hex head screw at this grade and size serves as a structural fastener within the floor saw's assembly, securing components that must remain firmly joined under the vibration and load generated during concrete or asphalt cutting. A worn, stripped, or incorrect-grade fastener in a high-stress location can allow components to shift, accelerating wear on surrounding parts and compromising operator control of the machine. Using the correct OEM-specified screw ensures the joint maintains its designed clamping load through normal service cycles.
