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

FINISH: Passivated per AMS 2700, type II or type VIII, + 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 80TC4, except tensile strength as tabulated and self-locking torque restricted to 5 reusability cycles 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:THCR 54 CD-BACN) or «CS» for passivated plus solid film lubricant (ex:THCR 54 CS-BACN).
