Elizabeth ★★★★★

The black oxide finish on these M2.5 screws is nicely uniform, and the hex drive seats perfectly without stripping. I used them for a jig build and the 12.9 grade steel feels incredibly tough for such a small fastener.

James P. ★★★★★

I needed a small, precise fastener for a jig I'm building and these button head screws fit the bill perfectly because the 12.9 alloy steel feels really tough when I tighten them down.

Ava ★★★★★

Finally, a batch of M2.5 screws that actually seat fully without stripping—these 12.9-grade alloy steel ones have a precise hex drive that grabs the bit perfectly. Used them to secure a metal bracket, and the black oxide finish looks clean and professional.
