براغي رأس كبس M10-1.25 X 100mm | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مؤكسد أسود حراري (50 / عبوة)

The hex socket drive on these M10 cap screws fits my Allen wrench perfectly, no stripping issues at all. The thermal black oxide coating seems durable and hasn't flaked off during assembly of a jig I'm building.

Used a handful of these on a heavy-duty jig I'm building, and the 12.9 alloy steel feels seriously overbuilt compared to standard hardware. The partial threading makes alignment a breeze, and they cinch down with satisfying torque.

The black oxide finish on these gives them a nice, uniform look that makes my jig builds feel more professional. Threads are clean and the partial threading gives me plenty of grip for tight assemblies. Just wish they’d arrive in a sturdier box since a few rattled around during shipping.
