I was worried the black oxide might rub off, but after installing a dozen of these in a jig they still look and feel great. The threads are clean and start easily without cross-threading.

The hex socket drive fit perfectly on my socket wrench, making installation into a jig assembly much quicker than I expected. These #10-24 screws have a nice solid feel thanks to the alloy steel, and the black oxide finish looks clean on my tooling setup.

Finally got around to replacing the factory bolts on my drill press table with these, and the black oxide finish is a nice touch for resisting shop grime. The hex drive made torquing them down into tight spots a breeze.
