براغي رأس كبس HOKO-KROME 87113 M6-1 X 45mm | محرك سداسي برأس مسطح | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

The black oxide finish on these screws is consistent across all 100 pieces, which matters when building a jig that has to look clean. They threaded smoothly into tapped holes without binding. Exactly what I needed for a precision tooling project.

Needed a batch of M6 screws for a tight-clearance assembly and these flat head socket caps fit perfectly. The black oxide finish looks clean and seems more consistent than what I've seen on other budget fasteners.

The thermal black oxide finish on these M6 socket caps looks sharp and seems to hold up well against scratches during assembly. I've used them on a jig I'm building and the flat head sits nice and flush, which is exactly what I needed for a clean fit.
