All I know this is a M3 thread pitch screw but length of threaded + shaft of the screw to underside of the head is requested.
I did find original hard drive caddies for my pair of 600 and 600e with hard drive screws (4 screws each).

Thanks & cheers, thinkpadcollection.

I should have an HDD cover screw for the 600 series at home. If you can hang out for a couple of hours I'll measure it for you.

edit: While it doesn't provide all of the dimensions you are looking for, this could be useful: http://forum.thinkpads.com/viewtopic.php?t=67743

Sorry for the delay; RL has interrupted this task.

Here's a photo and dimensions for the HDD screw from one of my 600X machines:
