براغي رأس سداسي M14-1.5 X 50mm | فئة 8.8 فولاذ مطلي بالزنك | ملولبة جزئيًا (50/عبوة)

Wrenched these onto a steel bracket this weekend and the zinc coating held up fine against my impact gun. The 50mm length gave just enough bite for the threaded section to grab cleanly without bottoming out.

The partial threading on these M14 bolts makes alignment a breeze, and the zinc coating looks uniform across all 50 pieces. I torqued them to spec on my press frame and the class 8.8 steel held without any give.

The zinc plating on these held up perfectly when I torqued them down with an impact wrench, no marring or peeling. The partial threads made alignment in the equipment frame much easier than full-thread bolts would have.
