مسامير رأس سداسي M12-1.75 X 130mm | فئة 10.9 فولاذ مطلي بالزنك | ملولبة جزئيًا (25/عبوة)

Installed these on a heavy-duty frame bracket and the Class 10.9 steel feels rock solid under torque. The zinc plating has a nice, even finish with no flaking during installation.

The partial threading on these M12 bolts makes them perfect for my equipment build where I needed full thread engagement without the shank binding. They drove in cleanly with a socket wrench and the zinc coating looks like it’ll hold up well.

Broke a cheap bolt on my press jig, so I grabbed these 10.9s—the zinc coating is holding up nicely under the wrench, and the partial thread gives me just enough grip for heavy clamping without bottoming out.
