Product Features & Fitment

Engineered for professional HVAC replacement and repair, the FASCO H10 hex hub features a robust construction built to withstand high rotational torque and thermal stress. The 5/8-inch bore fitment slides smoothly onto standard 5/8" motor shafts, while the integrated set screw provides a firm, slip-resistant grip to preserve motor shaft integrity over time.

This hub is required for mounting interchangeable-hub style condenser and unit heater fan blades (such as 3-wing and 4-wing aluminum blades). Using a dedicated hex hub ensures perfect centering of the fan blade assembly, reducing noise, balancing load distribution, and extending the operational lifespan of the fan motor.
