براغي رأس سداسية M4-0.7 X 16mm | فولاذ فئة 8.8 مطلي بالزنك الأصفر | ملولبة بالكامل (800 / عبوة)

The yellow zinc coating on these hex heads is even and consistent, and every screw threaded smoothly into my M4 nuts without any binding. For a bulk pack, the quality control on the threads is surprisingly good—I only found one slightly off piece out of the whole box.

I needed a large batch of M4 screws for a project and these arrived neatly packed and uniform in thread. The class 8.8 steel feels sturdy, and the yellow zinc finish should resist corrosion well enough for my shop jigs.

These hex bolts are exactly what I needed for a small machinery repair project. The Class 8.8 rating gives me confidence they'll hold up under load, and the yellow zinc finish looks clean.
