HOLO-KROME 86003 M3-0.5 × 10mm براغي رأس مقبس | رأس زر بمحرك مقبس سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

The black oxide finish on these screws is really consistent across the whole pack, which is nice for a clean look on my 3D printer carriage. I've used about half of them so far and the hex drive engagement feels solid every time.

Needed a handful of these for a jig fixture I was building, and the black oxide finish feels really durable and should resist rust nicely. They fit perfectly into the tapped holes with no binding at all.

Bought these for some small tooling repairs and the black oxide finish held up well against the threads, no binding or galling during installation. Fit perfectly in my M3-0.5 tap without any wiggle.
