The Cornell .75NC x 2.00″ Lockscrew Kit is a replacement fastening component for compatible Cornell 6NHTB pump impeller assemblies. The lockscrew is used to secure the impeller to the pump shaft and works with the impeller washer and related hardware to maintain a properly assembled rotating system.

Cornell parts documentation identifies the .75NC x 2.00″ socket-head 18-8 stainless steel lockscrew as Part #A14382-12-SD.

The lockscrew is subjected to significant clamping forces and operating loads while securing the impeller. During pump rebuilding or impeller service, the fastener should be inspected for damaged threads, corrosion, deformation, or other signs of wear. Using the correct lockscrew helps ensure the impeller is properly secured to the shaft.

Because Cornell uses different lockscrew lengths in similar pump assemblies—including a .75NC x 1.75″ lockscrew in certain 6NHTB19 configurations—verify the existing fastener and required 2.00″ length before ordering.
