Charlotte ★★★★★

The black oxide finish on these M3 screws is perfect for my precision assemblies—no glare and they don't corrode. The 12.9 alloy steel feels rock solid when torqued, and having 600 in one pack means I won't run out mid-project.

Edward ★★★★★

The black oxide finish on these is perfect for the jigs I’m building—no glare, and they thread cleanly into tapped holes without any binding. A full 600 count means I’ve got plenty left over for future projects, which is a huge plus.

Ella N. ★★★★★

These little M3 screws are perfect for jig building; the black oxide finish looks sharp and they thread cleanly without galling. A full 600 per pack means I've got plenty for the next several projects without reordering.
