Overview
|
Cage type. Permit mounting of aircraft instruments from
the front of the panel. No charge in panel or instrument design required. Non-magnetic (speed nut is brass; cage is phosphor bronze). Conform to MIL-N-3336. Cage is easily compressed with finger-pressure to allow insertion of legs into clearance holes. When fully inserted and pressure is released, legs spring apart; retain SPEED NUT in screw-receiving position. Turned down corners hold firm against force of in sert ing screw and screw-tightening torque. All instrument mounting nuts listed below take a 6-32 machine screw. Additional Info: the thread size is the same on each nut, but the instrument bezel thickness can be different per gauge. They are ordered by the back bezel thickness. They are inserted from the back, and they have ears pointing out that slide into a groove between the front and back bezel to stay in place. |

This p/n was supposed to be the correct fastener for a Mid Continent turn coordinator per the notes on the web site for the turn coordinator. Its not. Its too short.

No screws included?? Had to get screws, and run a tap on them all to get them to work. Would have been really helpfull if the screws were included!

they work.
Pefect for those mounting nuts that fall off in the back of the instrument panel when replacing/removing instruments. Excellent directions and sizing instructions given by AS&S.
OK
I knew what I wanted and that’s what I got.
Great item that can save many hours of frustration compared to trying to thread a traditional nut. Well worth the money.
This type of hardware design is under appreciated. always provides good instrument mounting.
