Key Features
- Genuine OEM Fastener Integrity — Manufactured to Husqvarna's exact thread pitch, flange diameter, and material hardness specifications, ensuring consistent clamping force and resistance to loosening under vibration.
- Broad Cross-Family Compatibility — A single part number that serves both demolition robots (DXR140, DXR145) and a wide range of floor saws (FS3500G, FS400LV, FS5000D, FS5000, FS600E, FS7000D, FS7000DL, FS7000DMT) as well as the MS610 masonry saw.
- Drop-In Hardware Replacement — The integrated flange seats flush against mating surfaces, distributing load evenly and eliminating the need for an additional washer during installation.
- Vibration-Resistant Connection — The flange profile resists backing off under the sustained vibration loads generated by floor saws and demolition robots, maintaining secure assembly integrity throughout heavy-duty operation.
- Structural Security Under Load — Using the correct OEM nut ensures that critical assemblies remain properly torqued, preventing premature wear on mating threads and connected components.
A hexagon nut flange is a fastener that combines a standard hex nut with an integrated flanged washer base, allowing it to distribute clamping load across a wider surface area than a conventional nut alone. On heavy-duty construction equipment such as floor saws and demolition robots, fasteners like this are subjected to continuous vibration and mechanical stress, making the correct specification essential. When an incorrect or worn nut is used, the risk of joint loosening, thread damage, and component misalignment increases — potentially leading to unplanned disassembly or structural failure of the connected assembly.
