Key Features
- Genuine OEM Zinc-Plated Construction — Manufactured to Husqvarna's specification with a zinc-plated finish that resists corrosion in wet cutting and dusty jobsite environments typical of floor saw operation.
- Correct 3/16 Sizing for Direct Installation — Matches the exact fastener size used in the PRO65G assembly, seating flush against mating hardware without shimming or modification.
- PRO65G Floor Saw Fitment — Confirmed compatible with the PRO65G floor saw; cross-reference part number 539300251 against your parts diagram before ordering to verify the correct application point.
- Fastener Integrity Under Vibration — Lock washers resist fastener back-off caused by the continuous vibration generated during concrete and asphalt cutting, helping maintain structural torque across the saw's assemblies.
- OEM Part Number Assurance — Using the correct Husqvarna OEM washer eliminates the guesswork of aftermarket sizing variations, ensuring the fastener stack-up behaves as engineered.
A lock washer is a small but critical fastener component positioned between a bolt or nut and the mating surface to prevent loosening under vibration and load. In a floor saw like the PRO65G, where sustained engine vibration and blade forces are transmitted through the frame and assemblies, properly torqued fasteners held in place by correctly sized lock washers are essential to safe and stable operation. A missing, damaged, or incorrectly sized washer can allow fasteners to back off over time, leading to loose components, misalignment, or accelerated wear at the affected joint.
