Emma ★★★★★

The black oxide finish on these M2 screws is consistent and looks great against the aluminum on my project. They thread smoothly into tapped holes without binding, and the hex socket drive gives a solid grip for my small driver. These 4mm lengths are perfect for securing thin brackets in precision a

Lucy P. ★★★★★

Putting together a custom jig for a small CNC project, these little screws were exactly what I needed. The black oxide finish looks great and seems durable. The threading is clean and consistent across all 400 pieces, which saved me a lot of time.

Joseph ★★★★★

The hex socket drive grips the Allen key perfectly, and the black oxide coating gives them a clean, uniform finish that looks great in my fixture builds. For the price per piece, these are a solid deal.
