How To Order: Standard Insert Material and Finish: 303 CRES (passivated). No identifying marks on insert. Standard Kees Material: 302 corrosion resistant steel. Other materials available by special request. This ordering code may be used for all inserts in this section except for RKKA and RKK series inserts on Page 16 which are supplied in carbon steel only. These should be ordered by part numbers as tabulated. All others may also be ordered by part numbers tabulated unless a special finish, length or material is required. In this case, use the ordering code below.

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.

  1. The suffix, SPNAS added to KN Part No. or S added to NAS Part No. indicates Silver Plate per AMS 2410.

  2. Use (L) in Part No. ONLY if Internal Thread Locking feature is required.

  3. “J” code as in KNCA0256J designates threads manufactured to MIL-S-8879.

  4. Replace “**” with one of the following suffixes: “SY” for MS parts

“SZ” for NAS parts
