M12-1.75 X 60mm براغي ذات رأس سداسي | فئة 10.9 فولاذ مطلي بالزنك | ملولبة جزئياً (100 / عبوة)

The partial threading kept these bolts from bottoming out in my lathe's blind holes, which was exactly what I needed. They drove in smoothly with a standard socket, and the zinc coating looks clean and uniform.

Needed these for a heavy equipment repair, and the partial threading made installation much easier in tight spaces. The zinc coating looks durable and the 10.9 steel feels plenty strong for the job.

I've been using these for a heavy machinery assembly project, and the 10.9 grade steel holds up well under torque without stripping. The partially threaded design makes them perfect for clamping thick parts together.
