Key Features
- Genuine OEM Fastener Grade — manufactured to Husqvarna's exact torque and thread specifications, ensuring the correct clamp load and material strength for each application
- Integrated Flange Design — the built-in flange distributes load across the mating surface without a separate washer, simplifying installation and maintaining consistent seating
- Broad Equipment Compatibility — fits CRT48 and CRT48PS power trowels, BMG555, BG250, BG250P, BMG2200RC, and PG8P floor grinders, MS610 masonry saw, BMP4000RC floor shaver, BS110 and BS75 floor scrapers, and the SoffCut5000 early-entry saw
- Structural Holding Integrity — a correctly fitted flange nut keeps assemblies securely locked under vibration and load; a stripped or incorrect fastener risks component loosening and equipment damage mid-operation
- Direct OEM Replacement — matches the original thread pitch, diameter, and flange geometry for a straightforward swap with no modification to surrounding hardware
A flange nut is a hex nut with a wide, integrated circular flange on one end that acts as a built-in washer. This flange spreads the clamping force over a larger surface area, reducing the risk of loosening under vibration and protecting the mating material from damage. On equipment like power trowels, floor grinders, and early-entry saws — all of which operate under continuous vibration — using the correct flange nut is critical to keeping assemblies tight and properly aligned. A worn, damaged, or mismatched fastener can allow components to shift during operation, leading to accelerated wear on surrounding parts and potential safety hazards.
