David ★★★★★

Used a handful of these to fix a jig that keeps getting knocked around, and the socket drive bites better than the hex head stuff I had before. The thermal black oxide hasn't chipped or faded after a week of assembly and disassembly, which surprised me for the price. Definitely my go-to for M3 faste

Riley D. ★★★★★

The hex drive on these M3 screws fits perfectly with my hex keys, making assembly on my 3D printer jig much easier. The 12mm length was exactly what I needed for securing the aluminum brackets. Nice consistent threading throughout the whole package.

Sebastian J. ★★★★★

The black oxide finish on these M3 screws gives them a professional look, and the hex socket drive made installation much easier than dealing with slotted heads. I used them for a small jig project, and the 12mm length was perfect for the assembly. A solid pack of hardware for any precision work.
