Daikin-McQuay 4NKE7968 Tinnerman Nut

The Daikin-McQuay 4NKE7968 Tinnerman Nut is a critical OEM replacement part designed for high-vibration HVACR environments. Engineered for precision, this U-type speed nut (also referenced as part 62XZ01) functions as a self-retaining fastener that replaces traditional threaded nuts and lock washers. It is a functional replacement for the 4NKE8447 and is commonly utilized in McQuay AV003B units and various industrial air conditioning and heating systems.

Constructed from high-strength spring steel with a corrosion-resistant coating, the 4NKE7968 provides a secure, permanent grip on thin sheet metal panels. Its unique arched base elastically deforms during installation, applying constant tension to the screw threads to prevent loosening due to thermal expansion or mechanical vibration. This HVAC fastener allows for rapid assembly without specialized tools, making it an essential component for technicians performing field repairs or panel installations on Daikin Applied equipment.
