IFD440 / GNS430 connector retaining screw type?

[tass]

Does anyone know what kind of screw holds the connector retainer on an IFD440? These are the screws whose heads you can see at the back of the tray after sliding the unit out (see pic).

After adding a couple of pins and trying to get the connector reattached, I dropped a screw and it must have slid into another dimension.

Its just a stainless cs 4-40 screw about 5/16” long. I believe it’s an MS5159-16.

Thank you!

I assume you meant MS51959-16. I'll get some and update as to how they fit.

Before I had a chance to get this screw, I was pulling out my seats while getting the conditional inspection done and found the lost one!

So I can't confirm whether MS51959-16 is the correct screw.
