Suggestion, a screw for a spacer pin

[dmalenic]

Mine bottom came with 10 M2.5 screws but no M2 screws. The spacer pin requires M2 screws. I have invented a small Rube Goldberg machine to fix the spacer pin ;-).
Indeed, the documentation does not mention M2 screws, but shipping bottoms with 8 M2.5 and 1 M2 screw would probably be better.

Same here, how to mount the SSD ???

My "solutions"; use them at your own risk ;-).

1. I managed to find one M2 screw, but its head was too narrow, and it was falling through the hole in the bottom. To prevent it, I used one M3 washer. The head of the screw was just wide enough not to slip through the hole of the M3 washer.
2. Use one M3x6 bolt with two nuts. Instead of a spacer, put one nut between the disk and the bottom. If you have nylon nuts and bolts, that's even better.

I am still looking for the correct M2 screws.

An additional remark:

The Google Coral TPU in AI Bottom is fully protected between the bottom and the Raspberry PI. I was surprised to find that the SSD drive on a DriveHat Bottom sits on the underside of the bottom together with the most accompanying electronics, i.e., it is exposed.

Interestingly, there was one fitting screw in my package. It took some trial and error to pick it from the others, however.

Actually, two more screws don't seem to fit the distances, so perhaps I got three drive screws?

Many SSD external enclosures use this method of retaining the SSD. One screw from the bottom retains the spacer, and a slot at the top of the spacer retains the SSD. There is no need for a screw on the top. The hole is there for manufacturing reasons as it’s much simpler to tap a through hole.
A printed quick install guide, or a printed page with a link or QR to online documentation, would go a long way to assisting users with these issues. My Pineberry Pi hat (bottom) arrived in an empty cardboard box but it was first run production so that may have changed.

Seems problem got solved with a different spacer.

I got a HATDrive! Top and a HATDrive! Bottom 3 days ago. Both deliveries have a M2.5 spacer for the SSD. To have some freedom changing the SSD, for the HATDrive! Top I soldered the brass spacer to the 2242 position and filed down the top to be able to insert the notch from the SSD and fix it with a screw.
