براغي رأس مقبس M6-1 X 10mm | محرك سداسي | ملول بالكامل | فئة 8.8 فولاذ سبائكي أكسيد أسود حراري (400 / عبوة)

The black oxide finish on these screws is really uniform and gives them a nice, professional look for fixture work. They threaded smoothly into every tapped hole without any binding, which saved me a lot of time on a recent assembly.

I needed a batch for a custom jig I was building, and the fully threaded length on these M6 screws worked perfectly for securing thin plates. The black oxide finish seems durable and gave them a clean, professional look right out of the package.

Installed these into a precision tooling fixture and the hex socket drive engaged perfectly without stripping. The thermal black oxide finish seems durable and gave them a professional look straight out of the bag.
