براغي ذات رأس مقبس M22-2.5 × 120 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ سبائكي من الفئة 12.9 مؤكسد أسود حراري (10 / عبوة)

These class 12.9 screws are exactly what I needed for a heavy-duty jig I'm building. The partially threaded design made alignment much easier, and the 120mm length gave me plenty of grip. Total overkill for most jobs, but perfect for when you need serious strength.

The black oxide finish looks great and seems tough, and the hex socket drive grabbed my Allen key perfectly without any stripping during install. These are holding up well on my precision assembly table, and the 12.9 alloy steel feels properly hardened for the torque I’m putting on them.

Put these on a heavy-duty jig I’m building, and the hex socket drive made installation easy even in tight spots. The black oxide finish looks solid and should resist corrosion well for the shop environment.
