Key Features
- Genuine OEM Fastener Grade — manufactured to Husqvarna's exact torque and thread specifications, ensuring the clamping load and flange bearing surface perform as the machine was designed to require.
- Integrated Flange Design — the built-in flange distributes clamping force evenly across the mating surface, eliminating the need for a separate washer and simplifying reassembly.
- Broad Cross-Family Compatibility — fits DXR-series demolition robots, FS-series floor saws, and T4000GP dust and slurry equipment, making this a widely used fastener across Husqvarna's construction lineup.
- Structural Integrity Restored — a correctly torqued flange nut maintains joint preload on critical assemblies; a worn, stripped, or missing nut can lead to component loosening, vibration damage, and costly secondary failures.
- Direct OEM Replacement — matches the original thread pitch, hex size, and flange diameter so this nut installs straight onto existing studs and bolt patterns without alteration.
A hexagon nut with an integrated flange is a structural fastener used throughout heavy construction equipment to secure assemblies that must resist vibration, shock loads, and repeated stress cycles. The flange acts as a built-in load-spreading washer, distributing clamping force over a wider area to prevent the nut from pulling through or loosening under dynamic loads. When this component is damaged, corroded, or missing, the integrity of the bolted joint is compromised — potentially allowing critical components to shift or separate during operation.
