براغي رأس سداسي M12-1.75 X 40mm | فولاذ فئة 8.8 أصفر زنك | كامل الخيوط (100 / عبوة)

I needed some heavy-duty bolts for mounting a motor mount, and these M12 hex heads fit the bill perfectly. The 8.8 steel feels solid, and the yellow zinc coating gives a nice, even finish.

Used these to secure a motor mount on a workbench, and the 8.8 grade held up perfectly under vibration with a socket driver. The hex head gave a snug, no-slip fit, and the yellow zinc coating still looks clean after assembly.

The yellow zinc coating is definitely a plus for outdoor equipment—no rust after a few weeks of rain. They’re fully threaded and drive in cleanly with a socket, though I wish the hex head had a bit more bite for stubborn spots.
