براغي رأس كبس M12-1.75 × 20 مم | محرك سداسي رأس زر | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 مطلي بالزنك (100 / عبوة)

These M12 button heads are exactly what I needed for a jig I was building—the fully threaded design gave me better grip than shoulder bolts would have. The Class 10.9 alloy steel feels really solid for the price, and the zinc plating looks clean.

The hex socket drive seated perfectly on my wrench without any wobble, and every single one of the 100 screws threaded cleanly into my jig fixture. Class 10.9 strength gives me real confidence for the tooling loads I'm putting on these.

The zinc plating is holding up nicely after a week of use in my jig setup, and every single screw threaded in smoothly without any burrs on the threads. I bought these for a precision fixture and the 10.9 alloy steel feels plenty rigid under load, so I’m glad I went with a full box.
