Review on 50 Pcs Black Thumb Screws for PC Computer Cases - M3.5 6#-32 Thumbscrews by uxcell by John Bones

Needed them for a computer project or they would have gone back. AT LEAST half of them are curved. literally the shaft/rails are bent up almost 45 degrees. Now I know why they give you 50 for the price other companies charge for 15-25. Also, the base "part under the main thumb area" that actually holds your PCI card or chassis component is small. So if you have a card such as a GTX 1080ti FTW3 with a large hole in its PCI bracket, you'll want to drop that little base into the hole rather than grab onto it and secure the card firmly in the case.
