The black oxide finish is even and consistent across all 100 pieces, so they look sharp in my jig setup. The socket drive seated perfectly with my hex wrench on every single one, no stripped or sloppy fits right out of the package. For precision tooling work, these feel as solid as anything I've use

I've been using these flat head screws for mounting brackets on my workbench, and the black oxide finish has held up nicely without any rust so far. The alloy steel feels sturdy enough for precision assemblies, though I wish the package had a few extra spares for the price.

These are sturdy little screws with a nice, even black oxide finish that hides scuffs well. Installed a handful into some aluminum tooling without any stripping or wobble. Would’ve been nice if the package had a few extra, but the quality is there for the price.
