مسامير رأس سداسية M12-1.25 X 80mm | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئياً (50 / عبوة)

I needed a partially threaded bolt for a heavy jig I’m building, and the zinc plating on these M12s feels smooth and corrosion-resistant right out of the pack. They threaded easily into my tapped steel plate with no binding, and the hex head held tight under a torque wrench.

The hex heads grabbed my 13mm socket cleanly with zero rounding, even on the two I torqued down tight. Zinc plating looks uniform and hasn't flecked after a week of shop use on a jig frame. Solid buy for the money.

The partially threaded design made seating these in my equipment frame a breeze, and the zinc coating looks clean and uniform across all 50 pieces. They torqued down smoothly with a socket and haven't budged since.
