براغي رأس سداسي M16-2 X 340mm | درجة 10.9 فولاذ عادي | ملولبة جزئيًا (4 / عبوة)

The partial threading on these M16 screws made cinching down my heavy equipment mount much easier than with fully threaded options. They drive smooth with a standard socket and feel incredibly solid for the price.

The partially threaded design made seating them into the frame a lot easier than fully threaded bolts. The hex heads grabbed my socket wrench cleanly with zero stripping, and the 10.9 steel feels properly stout for the money.

These bolts handled the heavy equipment frame I've been welding without a hint of flex, and the Class 10.9 steel is clearly up to the task. The partial threading made alignment a breeze too.
