براغي رأس سداسي مقاس M12-1.75 × 90 مم | فولاد فئة 10.9 بزنك أصفر | ملولبة بالكامل (225 / عبوة)

These went on without any binding, and the yellow zinc finish looks clean and consistent across all 225 pieces. The fully threaded design gave me plenty of grip depth for a solid hold in the machinery frame.

The hex heads on these M12 bolts gripped my socket perfectly without slipping during assembly. Class 10.9 steel feels robust for the heavy machinery frame I’m building. The yellow zinc finish looks clean and should resist rust well.

Grabbed a box of these for a big equipment rebuild I had coming up, and the 10.9 grade held up perfectly under high torque. The yellow zinc coating looks consistent and seems like it'll keep rust away in our shop environment.
