براغي غطاء رأس سداسي M16-2 × 260 مم | فئة 10.9 فولاذ عادي | ملولبة جزئياً (5 / عبوة)

I was worried the hex head might strip under heavy torque, but it held firm during assembly. The class 10.9 steel feels solid, and the 260mm length was perfect for my equipment frame.

The partially threaded design made alignment way easier than I expected when bolting down a thick steel bracket. The hex head grabbed my socket cleanly with zero stripping, and the 10.9 rating means these aren't going to flex under heavy loads.

I needed some heavy-duty bolts for a press build, and the 260mm length with partial threading made alignment a breeze compared to fully threaded ones. The hex heads gave my wrench a solid grip without any rounding.
