Product Description

Nut-Hex Specifications

This OEM hex nut secures the blower impeller assembly to the motor drive shaft. This part is black, made out of metal, and is sold individually. Hex nut threads can become damaged, and ends can become rounded off over time. This is a symptom of fatigue and will require replacement. You will know this part is broken if the impeller is no longer able to spin with the drive shaft. There will be no airflow from the blower. Most of our customers rated this as an easy repair, all you will need is a wrench or socket and torque wrench. When installing your new hex nut on the impeller blower, ensure your torque to the manufacturer specs when securing it to the drive shaft.
