براغي M12-1.75 X 20mm ذات رأس أسطواني | رأس زر بمحرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 مؤكسد أسود حراريًا (100 / عبوة)

Finally found socket cap screws with a proper hex socket drive that doesn't strip out on the first use—these are exactly what I needed for my jig build. The fully threaded length gave me plenty of grip, and the class 10.9 alloy steel feels solid enough for heavy-duty machinery.

The black oxide coating feels really durable and the hex socket drive made installation a breeze on my jig setup. These M12 screws fit perfectly and held without any issues under heavy use.

For mounting a heavy duty vise on my milling machine table these screws threaded in perfectly and the black oxide finish looks clean and professional. The hex drive holds up well without stripping even under high torque.
