Daikin-McQuay 847003J Nut

Maintain the structural integrity of your air moving assemblies with the Daikin-McQuay 847003J Nut. This professional-grade fan blade lock nut is precision-engineered to secure fans and propellers directly to the motor shaft, providing a critical fail-safe against rotational loosening. Featuring a specialized M8 thread design, this flanged hex nut is built for high-vibration HVACR environments, ensuring that outdoor condenser fans and commercial air handlers maintain optimal alignment during continuous duty cycles.

As a direct OEM replacement part, the 847003J eliminates the risks associated with generic hardware that can shear or back off under thermal stress. This Daikin lock nut is compatible with over 2,000 unit configurations, including specific 3MKS, RXS, and RZQ series outdoor sections. For technicians performing preventative maintenance or motor replacements, utilizing this HVAC fan motor nut ensures a secure, tight fit that minimizes resonance and protects the motor bearings from premature wear caused by imbalanced or slipping blades.
