براغي رأس أسطوانية M10-1.5 × 65 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائكي فئة 12.9 مؤكسد أسود حراريًا (100/عبوة)

The black oxide finish is a nice touch—these screws fit into my jig setup without any binding, and the 12.9 alloy steel feels genuinely solid under torque. For a hundred pieces, the threading is clean and consistent across the batch.

The hex socket drive on these M10 screws makes installation straightforward with a standard Allen key, and the black oxide finish looks clean on my jig setup. Thread engagement feels precise even on the partial threads, no wobble at all.

Had to torque these down pretty hard and the hex socket didn't strip at all—the black oxide finish also kept them from rusting during assembly. Perfect for my tooling fixture project.
