THREAD: AS8879
MATERIAL: A286 corrosion resistant steel per AMS5732 or AMS5737 (UNS S66286).
HEAT TREAT: Rc 33-44
FINISH:

KFN511C(*) - Passivate per AMS2700, cadmium plate per AMS-QQ-P-416, Type II, Class 2, plus cetyl alcohol lubricant.
KFN511DL(*) - Passivate per AMS2700 and Kaylube molybdenum disulfide dry lubricant coat per AS5272.
KFN511E(*) - Passivate per AMS2700, silver plate per AMS2410, plus cetyl alcohol lubricant.
KFN511J(*) - Silver plate per AMS2410.
KFN511K(*) - Lubeco 905 solid film lubricant.
KFN511V(*) - Lubeco 2123 solid film lubricant.

PERFORMANCE: KFS 1011, except as follows:

Axial tensile strength as tabulated.
Recommended seating torque as tabulated.
Maximum locking torque as tabulated.
Metallurgical examination (microstructure) required per 33A056.

APPLICATION: For use on standard to .032 oversize shank bolts.
PACKAGING: Parts are normally supplied in bulk packaging. Add "S" after dash number for spindle packaged nuts for use with K-Fast® automatic tools, or "SS" for parts on "short spindles" for use on lightweight K-Fast® automatic tools. Spindle packaged parts apply thru -5 nuts only.(Example: KFN511C3S or KFN511C3SS).
NOTES: "C" and "W" dimensions apply prior to forming self-locking feature.
