براغي مقبس سداسي M3-0.5 × 16 مم | رأس مسطح محرك مقبس سداسي | ملولب بالكامل | فولاد سبائكي فئة 10.9 أكسيد أسود حراري (900 / عبوة)

The black oxide finish on these M3 screws is a nice touch—no glare when working under shop lights. Threads are clean and uniform across the whole box, which makes assembly go smoothly. Very happy with the quality for precision jig work.

I was pleasantly surprised by the consistent thread depth across all 900 screws, which made assembly on my jig so much smoother. The black oxide finish feels durable and hasn't shown any wear after a few weeks of use.

The hex socket drive on these M3 screws grips the Allen key perfectly without any slipping, even when torquing down to spec. The black oxide finish looks clean and has held up well during assembly of a few precision fixtures I'm working on.
