Notes:
- Anti-seize compund per MIL-A-907 applied to internal
thread. - Mechanical properties of nut plate meets the requirements
of procurement specificatiom MIL-N-25027. - The assembly provides a bearing surface for the nut within
the cage. - Shape within envelope shown optional.
- Threads per MIL-S-8879 except in locking area and prior to
lubrication. - Minimum assembly height (E) not specified, limited only by
strength requirements.
- Anti-seize compund per MIL-A-907 applied to internal
Notes:
- Float of nut portion of assembly is 0.020 minimum radially
from centered position. Nut body is capable of engagement with a bolt in the maximum misaligned position. - Nut plates are similar to the dimensional envelope specified
in NAS 1789. - Locking torque: The nut element of these assemblies shall be
capable of 250 seated, usable cycles when tested per the requirements of CAL-STD-0232.
