Abigail P. ★★★★★

I needed some tiny fasteners for a precision jig project and was pleasantly surprised that these M2.5s came pre-lubed enough to drive smoothly with a hex key. The black oxide finish feels durable and hasn't scratched off during installation.

Abigail C. ★★★★★

The threading is clean and consistent across all 600 pieces, which saved me a ton of time sorting for a tolerance-sensitive tooling setup. The black oxide finish looks proper and hasn't chipped during handling.

Riley ★★★★★

Installed these in a jig I was building for a small CNC project, and the hex socket drive made tightening them a breeze. The black oxide finish looks clean and professional, and at 600 screws for the price, I’ve got plenty for future builds.
