براغي رأس سداسي M4-0.7 X 12mm | فولاذ فئة 8.8 مطلي بالزنك الأصفر | خيط كامل (1000 / عبوة)

The hex heads fit my socket wrench perfectly, making assembly work on a small jig much faster. The yellow zinc finish seems durable, and having a full thousand pieces means I won't run out mid-project.

I needed a bulk supply for assembling custom brackets and these M4-0.7 x 12mm hex heads are perfectly consistent in thread quality. The Class 8.8 steel feels solid under a torque wrench, and the yellow zinc coating looks uniform across all thousand pieces.

The yellow zinc coating is really consistent across all 1000 pieces, and the hex heads are sharp enough that my socket grips them without any stripping. Threads are clean all the way down, so they drove into my steel brackets without a single cross-threaded start.
