براغي HOLO-KROME 64016 #8-32 X 1/4" ذات رأس أسطواني | محرك سداسي داخلي | فولاذ سبائكي بأكسيد أسود حراري (100 / عبوة)

Used a handful for mounting a small motor mount on a 3D printed jig, and the black oxide finish held up well without stripping. The hex drive fit snug on my Allen key, nice consistent threads throughout the whole pack.

The head sits flush in my jig without any wobble, and the thermal black oxide gives them a nice, even coating that resists fingerprints. These little button heads are exactly what I needed for a precision assembly.

The black oxide finish on these is so even and clean, they look great in the jig I built. The socket drive grips securely without any stripping, even under a good bit of torque.
