براغي رأس سداسي مقاس M14-2 × 50 مم | فولاذ عادي فئة 8.8 | ملولبة جزئيًا (50 / عبوة)

The threads cut cleanly and the hex heads seated snugly with a standard socket wrench, no stripping or wobble. Used a full pack on a conveyor frame and not one bolt gave us trouble, so the 8.8 steel grade feels up to the task.

I swapped out old bolts on a press fixture with these 50mm hex heads, and the class 8.8 steel holds torque without stripping. The partially threaded design made alignment much easier than fully threaded ones I’ve used before.

These M14-2 bolts are exactly what I needed for reassembling my milling machine's base. The partially threaded shank made alignment a breeze during installation.
