Additional Information

The snowblower flange nut, part number 585802801, threads onto a bolt to secure components while the integrated flange helps spread the load across the mounting surface. This design helps maintain alignment and reduces loosening during operation.

You might notice fasteners backing off over time, increased vibration near mounting points, or components shifting slightly under load. Stripped threads, corrosion, or a missing flange nut can also prevent hardware from staying tight.

Disconnect the spark plug wire before beginning the repair. The nut installs near metal brackets and rotating components, so work gloves can help protect your hands during removal and installation. Tighten the nut securely to the specified torque before reconnecting the spark plug wire.

Flange nut 585802801 replaces part numbers 98000129, 571P, and 166785.
