Can't beat the price!
Luckily enough, these were the exact product I needed. I used them to repair some threaded holes on a 3D printer. Rigidity was extremely important, and these worked great! Comparing these to the other options on Amazon yields an easy win. E-Z LOK sells carbon steel versions for 10 for $10, and for stainless, 5 for $10 (both have a slightly larger outer diameter). Considering that these are 20 for $10, they really can't be beat. Despite these being advertised as self-tapping, I originally planned to tap the holes myself and purchased an M5 drill & tap. However, apparently the threading is not the standard M5 x 0.8, (it's probably M5 x 0.5) so I had bought the wrong size tap. However, they installed fine anyways, and I secured them in place with a drop of threadlock. Overall, best deal on Amazon.

These will work better than wood screws, as multiple teardowns will be required.
