براغي رأس سداسي M4-0.7 × 20 مم | فولاذ درجة 8.8 مطلي بالزنك الأصفر | ملولبة بالكامل (600/عبوة)

Packed 600 of these per order and the hex head fits a standard 7mm socket perfectly—threads are clean with no binding. Used them on a few stubborn brackets and the yellow zinc finish held up to light scuffing without flaking.

Finally got around to replacing all the old hardware on my workbench jigs, and these M4 hex heads drive in smoothly with a socket. The Class 8.8 steel feels sturdy enough for repeated adjustments, and the yellow zinc coating gives them a nice, consistent look across all six hundred pieces.

Used these to fasten some brackets onto a motor mount, and the class 8.8 steel held torque without stripping. The yellow zinc coating looks clean and hasn't shown any rust after a few weeks of light exposure.
