Customer Reviews (4.6 / 5 · 5 reviews)

Robert D. ★★★★★

I've been using these M2 screws for a few small jigs and the hex socket drive makes them really easy to tighten precisely. The 12.9 alloy steel feels much stronger than the standard stainless ones I used before.

Sebastian ★★★★★

The black oxide coating on these has held up perfectly through repeated assembly and disassembly on my precision tooling. All 400 arrived with consistent threading and clean hex sockets, and the 12.9-grade steel gives them a reassuring rigidity.

Emma ★★★★★

These little M2s are perfect for my jig builds—the black oxide finish looks clean and the hex socket drive makes them easy to torque down even in tight spots. 400 per pack means I won't be reordering for a while, and every single one threaded smoothly without any stripped heads.
