HowmetMATERIAL: A 286 (Z6NCT25) per AMS5731 or EN 2399.
FINISH:
MARKING: Parts marked with manufacturer’s symbol (SD), plus letter "C’’.
PERFORMANCE: NASM25027, except ultimate tensile strength and locking torque values applicable for 5 cycles. Code FP = Unit control for fluorescent penetrant inspection (ex.: PHCR510M-FP).
THREADS: In accordance with AS8879 before lubrication.
APPLICATION: These nuts have been designed to replace AN320 castellated nuts on critical aircraft control linkage. This design provides an increase in tensile strength while reducing weight substantially over similar parts.
