براغي رأس كبس M8-1.25 × 10 مم | رأس زر بمحرك سداسي داخلي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 أكسيد أسود حراري (300 / عبوة)

The black oxide finish on these is nicely uniform, and they seated perfectly into my drill jig without any wobble. I was glad to see the hex drive didn't strip on the first torque, which has been an issue with cheaper fasteners. For precision tooling work, these are exactly the quality I was hoping

Used a full bag to secure a jig frame on my milling table, and every single screw seated perfectly without stripping. The black oxide finish gives them a nice, uniform look and seems tough enough to resist oil stains.

The hex socket drive fits my Allen key perfectly, and the 12.9 alloy steel feels seriously tough for jig building. I grabbed a 300-pack and every single one came out of the box with a clean, consistent black oxide finish. Solid buy for the price.
