Notes from the standard
- The listing shows H twice, with the same value in both columns; it is given once here.
- Dash numbers match the NAS577 barrel nut they retain: 4A to 8A. The listing does not state the pairing; check the standard.
- Part number format as commonly written; check the standard for the exact format.
- Approved data governs. Use the nut the SRM, drawing or IPC calls for.
