براغي رأس سداسية M12-1.75 × 260 مم | فولاذ درجة 8.8 مطلي بالزنك | ملولبة جزئيًا (25 / عبوة)

The zinc plating seems decent and the threads were clean all the way down, which saved me time chasing them. Installed these on a press fixture yesterday without any issues.

The 260mm length was perfect for bolting down a heavy press, and the zinc coating seems sturdy enough to resist garage moisture. I used a socket on the hex head and it seated flush without any wobble.

The partially threaded design made these perfect for clamping down a heavy steel bracket I've been working on, and the zinc plating looks like it will hold up well. I used a socket on the hex head, and they threaded in smoothly without any binding.
