M16-1.5 X 55mm براغي رأس سداسي | فولاد فئة 8.8 عادي | ملولبة بالكامل (25 / عبوة)

The hex head on these cap screws fits my socket perfectly, making installation on a conveyor frame quick and stable. The class 8.8 steel feels solid and should hold up well under constant vibration.

The threading is clean and the hex head seated perfectly in my socket wrench without any stripping. These Class 8.8 bolts feel solid for the price, and the 25-pack covered my whole project with extras to spare.

I needed a full-threaded 55mm bolt for a heavy-duty jig I’m building, and these M16s fit perfectly with a solid hex drive. The 8.8 steel feels sturdy enough for the load, and the threading is clean all the way down. Exactly what I expected for the price.
