NOTES: 1. When Dry Film is not required on locking parts, add the suffix, N on NAS Part No., or NE on KN
Part No.
-
The suffix, SPNAS added to KN
Part No. or S added to NAS Part No. indicates Silver Plate per AMS 2410. -
Use (L) in Part No. ONLY if
Internal Thread Locking feature is required. -
“J” code as in KNCA0256J
