Key Features
- Correct Thread Specification — Cut to a 3/8-24 UNF thread profile, matching the fastener standard used in the PRO65G assembly exactly as Husqvarna intended.
- Zinc-Plated Finish — The Z/P coating provides corrosion resistance suited to the demanding environment of a walk-behind floor saw on wet or slurry-heavy cuts.
- Genuine OEM Quality — Sourced directly from Husqvarna as a factory-original component, ensuring the material grade and dimensional tolerances match the original hardware specification.
- Direct Assembly Fit — Drops into the existing fastener position on the PRO65G without rework, preserving clamp load and torque integrity across the bolted joint.
- PRO65G Floor Saw Fitment — Confirmed OEM fitment for the PRO65G floor saw, so you can order with confidence that this is the right part for your machine.
A hex nut at the 3/8-24 UNF specification is a fine-thread fastener used in applications where vibration resistance and precise clamping force are important — both common demands on a walk-behind floor saw like the PRO65G. The zinc plating protects the fastener from rust and surface corrosion, extending its service life even when the machine is used in wet-cutting conditions. Using a fastener of the correct thread pitch and grade maintains the integrity of the bolted joint; substituting an incorrect nut risks stripped threads, loosening under vibration, or component misalignment.
