براغي رأس سداسي M4-0.7 X 12mm | فولاذ فئة 8.8 عادي | ملولب بالكامل (10,000 / عبوة)

The hex heads sit flush in my wrench without any slip, and the Class 8.8 steel feels plenty sturdy for the motor mounts I’ve been bolting down. A full box of 10,000 is overkill for my bench, but the threading is clean all the way down, so every one drives in smoothly.

I needed these for a small robotics jig, and the fully threaded design let me lock in components exactly where I wanted. Class 8.8 steel holds up well under repeated wrenching, so I'm confident they won't strip out.

The hex heads grab a socket wrench cleanly without any slipping, which is exactly what I need for tightening them in tight spots. A full box of ten thousand means I won't be reordering for a long time, and the 8.8 steel feels properly sturdy for the price.
