I purchased Kennett Classic's TRS-80 Model II and for some reason the machine threaded screws that held the top casing to the chassis and the screws that hold the keyboard together are just...gone. They seem to be machine screws but I have no idea what dimensions they might be, so I'm hoping someone here might know so I can source replacements?
 
From the Model II Tech Ref, page 13, the keyboard screws are 6-19 x 3/4", page 12 says 'four thread forming and two machine screws'
page 139 (Parts list) shows 6-19 x 3/4" (6) and SFT 3-28 x 3/8" (2). Could swear they were all thread forming screws in the keyboard.

Page 177 "Case Assembly Parts List" shows Screw, 8-32 x 1/2" (2) and Washer, flat #8 (2).
 
Ah yeah, the keyboard screws are probably self-tappers, the ones for the case are definitely machine screws though. I'll look for these!
 
Try not to get stainless screws as the ones I've tried won't work with a magnetic screw driver.
