براغي رأس كبسولة M12-1.75 × 25 مم | محرك سداسي برأس زر | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 أسود حراري (100 / عبوة)

These M12 button head screws fit perfectly into my jig setup, and the black oxide finish looks clean and professional. The hex socket drive made installation straightforward with no stripping issues. A solid choice for precision tooling work.

The black oxide finish on these feels tough and even, and the hex sockets were clean and sharp—no stripped edges when torquing them down on the jig. For the price of a hundred, they’ve held up exactly as expected in my precision assembly work.

I’ve been using these on a few tooling fixtures, and the black oxide finish has held up well against minor abrasion. They drive smoothly with a hex key and the threads are clean.
