براغي ذات رأس سداسي M12-1.75 × 60 مم | فولاذ فئة 10.9 مع طلاء زنك أصفر | ملولبة بالكامل (50 / عبوة)

Installed a dozen of these on a heavy-duty jig frame and the 10.9 grade steel held up perfectly under full torque. The yellow zinc coating is a nice bonus for corrosion resistance.

The hex heads seated perfectly in my socket wrench, and the 60mm length was exactly what I needed for bolting down the motor mounts. Threads are smooth from end to end, and the class 10.9 hardness gives me confidence these won't strip under heavy torque.

The yellow zinc coating looks even better in person than in the photos, and the threading was clean all the way down on every single one I used. Took a bit of effort to find the right torque spec for these Class 10.9s, but they held up perfectly on my jig build. Only wish they came in a smaller pack
