These are cage-type nuts that allow an aircraft owner to mount instruments from the front of the panel. No change in the panel or instrument design is required. These are non-magnetic because the speed nut is brass and the cage is phosphor bronze. All instrument mounting nuts take a #6-32 machine screw and conform to MIL-N-3336.
Instrument mounting nuts permit the mounting of aircraft instruments from the front of the panel. It is easily compressed with finger pressure to allow the legs into the clearance hole. Once it is fully inserted and pressure is released, legs spring apart. Instrument thickness is .312.
