Shell Screws

Like every other modder out there, I save shell screws from scrap blasters and projects when I can, but you still can't always find the right ones.
Also, a lot of 3D printed blasters call for specific screw sizes so hopefully you can find what you need right here.
Sizes available are:
2.5 x 10
2.5 x 12
3 x 10
Price is for a pack of 10.
