  • K7000 Clinch Nut, Flush Mounted
THREAD: AS8879
MATERIAL: Carbon steel, heat treated.
FINISH: Cadmium plate per AMS-QQ-P-416, Type II plating and Kaylube molybdenum disulfide dry lubricant after plating per AS5272, Type I.
APPLICATION: Blind application where a hex nut is inaccessible for wrenching or where limited clearance prevents installation of an anchor nut. After installation, clinch nuts become permanently fixed and remain in position during disassembly. Clinch nuts may be used in thin sheets of such materials such as aluminum alloy, copper, brass or mild steel.

-4 shank lengths will produce torque and push out values slightly below those required by NASM25027.
