MATERIAL: A286 Cres per AMS 5732 or AMS 5737, heat treated to develop properties commensurate with nut performance requirements herein.

FINISH: Cadmium plated per AMS-QQ-P-416, type and class optional if lubricated nuts meet salt spray requirements of AMS-QQ-P-416, type II, + solid film lubricant.

LUBRICATION: Solid film lubricant per MIL-PRF-46010, type I, or AS 5272, type I. Lubricant shall meet the requirements of BPS-N-70.

PERFORMANCE: BPS-N-70, class 125TC4, except tensile strength as tabulated and self-locking torque restricted to 5 reusability cycies on a cross drilled bolt or stud. Control method according to BACN11N.

THREADS: Per AS-8879, prior to lubrication.

MARKING: Parts marked with manufacturer's symbol «SD» and «CD» for cadmium plated plus solid film lubricant + white paint (ex:PHCR 54 CD-BACN)
