براغي رأس مقبس M12-1.25 × 70 مم | محرك سداسي | ملولبة جزئيًا | فولاذ سبائك فئة 12.9 أكسيد أسود حراري (50 / عبوة)

The black oxide finish on these screws gives them a nice, uniform look and they threaded into my jig plate perfectly without any binding. Exactly the grip I needed for a heavy-duty assembly.

Wrapped up a jig rebuild this weekend and these socket cap screws fit perfectly in the threaded holes I had. The hex socket drive made tightening them down in tight spots so much easier than a standard bolt.

Used them on a tooling fixture where I needed the partial thread to pull two plates tight. The black oxide finish looks clean and the class 12.9 hardness feels right for the job. Only knock is the packaging—they arrived loose in a bag, not sorted by length.
