The black oxide finish is holding up nicely so far, even after a few cycles in my jig. The button head profile makes them easy to get a hex driver on in tight spots, and the alloy steel feels solid. Exactly what I needed for this precision assembly.

The black oxide finish on these screws is very consistent across the whole pack, which really helps with a clean look on my jig assembly. Fits the hex driver perfectly without any wobble, and at this price for a hundred pieces it’s a solid value.

I’ve been using these #10-32 x 1/4" socket cap screws for jig assembly, and the button head gives a clean, flush fit with a hex key. The black oxide coating looks sleek and hasn’t chipped during tightening.
