براغي ذات رأس أسطواني M10-1.5 X 80mm | رأس زر مع محرك سداسي | ملولبة بالكامل | فولاد سبائكي فئة 12.9 مع أكسيد أسود حراري (50 / عبوة)

The black oxide finish on these M10 socket cap screws looks professional and the hex drive engages my Allen key perfectly without any wobble. They drove smoothly into pre-tapped holes for my jig build, and the 80mm length was just right for bolting through a thick spacer.

Threads are clean and consistent all the way down, and the black oxide finish took a bit of wrenching without chipping. Tightened a few jig plates today and the 12.9 alloy steel felt solid in the socket, no stripping issues.

Used a few of these to secure a heavy-duty jig on my mill table, and the 12.9 alloy steel handled the torque without any issue. The hex socket drive made installation straightforward even in a tight spot.
