Sofia U. ★★★★★

I needed fasteners that could handle high torque without stripping, and these M3-0.5 x 16mm screws with the hex socket drive have held up perfectly in my jig setup—the black oxide coating also resists wear better than I expected.

Lucy ★★★★★

Used a full batch of these for a custom jig build and every single one threaded perfectly into the tapped holes. The hex socket drive grabs cleanly without any stripping, and the 12.9 alloy steel feels properly tough for my machine setup.

Riley ★★★★★

The black oxide finish on these M3-0.5 x 16mm screws looks even better in person, and the hex socket drive grabs securely without stripping. I’ve used about 80 of them so far for jig assembly and every single one threaded cleanly. At this price for 600 pieces, I’m stocked for years.
