Source notes and limits

  • Manufacturer cross-reference: NAS1291-5 → ESNA M52LF3324-5 (PDF p.18). This is a catalog mapping, not an independent determination of interchangeability.
  • Thread is joined to the exact ESNA part listed in the reviewed LF3324/LF3858 table. The controlling standard was not read; dimensions and strength of the standard part are not asserted.
  • Torque is not inferred from a thread or nut part number. The controlling installation instructions govern.
