HOLO-KROME 72042 #6-32 X 1/2" مسامير رأس مقبس | محرك سداسي | سبيكة فولاذ أكسيد أسود حراري (100 / عبوة)

Needed a reliable fastener for a jig I was building, and these cap screws fit perfectly with no burrs on the threads. The black oxide finish looks great and seems to resist light oil stains well.

I needed a fresh pack for a small jig I was assembling, and the hex socket drive made installation much easier than a regular slotted head. These feel solid and the threads cut cleanly into the aluminum without any binding.

The thermal black oxide finish on these #6-32 screws is impressively uniform and seems tough. I used them to repair a jig and the hex socket drove cleanly without stripping.
