Customer Reviews (4.8 / 5 · 5 reviews)

Christopher ★★★★★

The black oxide finish on these screws looks great and seems to resist wear better than plain steel ones I've used before. They've been perfect for securing jig components where I needed a clean, low-profile head.

Emma Q. ★★★★★

Finally, a set of M4 screws where every single one threads smoothly without any burrs. The black oxide finish on these 10.9 alloy steel cap screws is even and consistent, which is a nice touch for a precision assembly.

Ruby N. ★★★★★

Machine build came together without a single stripped head or mangled thread across the whole bag, which is exactly what I need for jig work. The black oxide finish feels properly grippy in the hex key, and the 10.9 hardness gives me confidence they won’t snap under load.
