براغي ذات رأس مقبس HOLO-KROME 64018 #8-32 × 3/8" | محرك سداسي برأس زر | فولاذ سبائكي أكسيد أسود حراري (100/عبوة)

The black oxide finish on these screws gives them a nice, uniform look and seems to resist surface rust well during assembly. I used a dozen of them to secure a small jig on my drill press, and the hex socket drove true without any cam-out. They're precisely threaded and hold snugly in tapped holes.

Finally, a hex key that doesn't strip the head—these button heads fit my driver perfectly. The 100-pack is great for filling up a jig without worrying about running short mid-project.

The black oxide coating on these screws feels tough and durable, and they seated perfectly in my precision assembly without any stripping. Exactly what I needed for a reliable hold on my machinery jig.
