براغي رأس سداسية M16-2 × 55 مم | فولاذ عادي فئة 10.9 | ملولبة جزئيًا (30 / عبوة)

These bolts fit perfectly into my milling machine's mounting flanges, and the partial threading made alignment a breeze. The 55mm length was exactly what I needed for a secure hold without bottoming out.

I needed these for a heavy machinery repair and the Class 10.9 steel held up perfectly under torque. The hex head gave my socket wrench a solid grip without any slipping.

The partial threading made all the difference when I needed to cinch down a thick flange plate—the unthreaded shank gave me a clean, full bite without any binding. These M16s feel rock solid in the hand, and the 10.9 steel took my impact driver's abuse without a hint of rounding on the hex head.
