Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Husqvarna's exact thread pitch and profile specifications, delivering the consistent clamping force this fastener application demands.
- Exact Drop-In Replacement — This thin-profile hexagon nut installs directly in place of the original, requiring only standard hand or wrench tooling.
- Broad Equipment Compatibility — Fits the DS900 concrete core drill, FS4800D, FS513, FS520, and FS524 floor saws, and the CG200 floor scarifier across Husqvarna's construction lineup.
- Correct Torque Retention — A properly spec'd OEM nut maintains the intended clamping load under vibration and load cycling, preventing loosening and component misalignment during operation.
- Secure Fastening Under Demanding Conditions — Core drilling, floor sawing, and scarifying all subject fasteners to sustained vibration; using the correct OEM nut ensures joint integrity is maintained throughout the work cycle.
A hexagon thin nut is a low-profile threaded fastener used where space constraints prevent the use of a standard-height nut, or where a specific clamping depth is required by the assembly design. In heavy-duty construction equipment, the correct nut specification — including thread class, material grade, and across-flats dimension — is critical to maintaining proper joint tension. An incorrect or worn nut can lead to loosening under vibration, fastener failure, or damage to mating components, all of which can interrupt operation and lead to more extensive repairs.
