Zoe Y. ★★★★★

I've been rebuilding a small jig and these M2s hold up way better than the zinc-plated ones I used before—the black oxide finish feels tougher and hasn't chipped even after repeated tightening. The socket drive is easy to seat with a hex key, and 100 pieces means I've got spares for the next project

Eli ★★★★★

These little M2 screws fit perfectly into the precision assembly jig I'm building; the hex socket drive made tightening them in tight spots much easier than I expected. The black oxide finish looks clean and seems durable so far.

Samuel ★★★★★

I needed some small screws for a jig I was building, and these M2-0.4 x 4mm cap screws fit perfectly. The hex socket drive made installation easy with a tiny Allen key.
