M12-1.75 X 70mm براغي ذات رأس أسطواني | رأس زر محرك سداسي | ملولبة بالكامل | سبيكة فولاذية فئة 10.9 مطلية بالزنك (50 / عبوة)

Had to replace some bolts on a heavy jig fixture at work, and these threaded in smoothly with no binding. The zinc coating looks even and seems durable, and the 10.9 grade gives me confidence they'll hold under load.

Hex drive seated perfectly on my wrench, no stripping even with a breaker bar torquing them down for a jig build. Threads ran smooth through the tapped holes, and the zinc finish hasn't shown a speck of rust after a few weeks in the shop.

The hex socket drive seated perfectly on my torque wrench, and the 10.9 alloy steel feels reassuringly rigid when I’m tightening down my jig fixtures. Zinc coating’s held up fine so far with no marring, even after a couple of oily shop days.
