Christopher N. ★★★★★

I needed tiny screws for a precision jig project, and these M2-0.4 x 3mm ones fit perfectly with their hex socket drive. The fully threaded design makes them easy to secure in tight spots.

John Y. ★★★★★

The black oxide finish on these M2 screws looks great and resists corrosion better than plain steel. They fit perfectly into my aluminum jig frame with no stripped threads.

Olivia ★★★★★

I got these for a small robotics project and the hex socket drive made installation super easy with my Allen wrench set. The 600-piece pack is great value and every screw threads smoothly without any binding.
