What it is
The Navien 20012771A is a hex flange nut used on Navien NPE-AWE and NPE-SWE series appliances. The integrated flange spreads the clamping load across the mating surface rather than concentrating it under the hex. It is a fastener component, not a functional assembly in its own right.
Signs this part needs replacing
- Rounded or chewed hex flats that will not take the correct torque
- Corroded, pitted or stretched threads
- Flange deformed, cracked or flattened
- Nut that has worked loose in service
- Weeping, staining or residue at the joint the nut secures
Before you order
- Confirm your appliance model and serial number against the fit list above
- Compare thread size and pitch with the nut removed from the appliance
- Check how many nuts the job requires before ordering
