Solved!
Go to SolutionScrew(s) specification(s) for Dell Latitude 5490
Does anybody know the screw specifications for the Dell Latitude 5490 for:
Back cover. Type (known - flat) , screw diameter, length, thread / pitch. Whoever worked on my refurb unit stripped the Philips "slot" on 2 of the screw heads of the black screws that secure the back cover. These appear to be M2 x 7mm, pitch unknown.
Hold down screw for the NVMe M.2 SSD. What is in there is a short flat head screw, but, it appears that a washer or pan head would be better. The installed screw appears to be a Philips M2 x 4mm*, pitch unknown.
*Estimate -- I did not measure this one.
Hold down screw for the SATA M.2 SSD in the WWAN slot. (Yeah, I got the drive to work.). Nothing was installed in the WWAN slot as I received the machine, so, not surprisingly, no screw... It appears that a washer or pan head screw would be best. Best guess would be that it should be a Philips M2 x 4mm*, pitch unknown.
*Estimate -- Nothing there to measure.

Welcome to the Dell Community @Saluki
Your manual should have all the screw sizes.
Best regards and good luck,

Ah, I looked in the wrong place. It's under "Removing and Installing Components"!
Specifically...
https://www.dell.com/support/manuals/en-us/latitude-14-5490-laptop%20/lat_5490_om/screw-size-list?guid=guid-6b799bad-5b0c-4c25-a930-b65b0154bf8d&lang=en-us
Interesting that all screws are flat head even when thin pan head or washer head would seem appropriate.
Thanks.
