M3 is a very typical screw size in the 3-D printing world. A box of all the different lengths comes in real handy when you’re working on 3-D printers. I’ve also had several prints that require these screws, including the Toro spin turbo by kocyns.

I modified a chair and needed longer screws did a little bit of research and found out that these were the exact screws that the chair used found them had a longer length which is exactly what I was looking for on. Amazon worked out perfectly. Now I have 24 extra screws. lol but still worth the money.
