M16-1.5 X 50mm براغي ذات رأس سداسي | فولاد فئة 8.9 مطلي بالزنك | ملولبة جزئيًا (25 / عبوة)

The hex head gave my socket wrench a solid grip, and the zinc plating on these Class 8.8 bolts is holding up perfectly in my shop setup. No stripping or corrosion after a week of use.

Installed these on a heavy-duty shelf bracket and the partially threaded design let me snug them tight without binding. The zinc coating looks uniform and feels sturdy—no flaking after wrenching them down.

These threaded into the M16 nuts I had with satisfying resistance, and the hex head grabbed my wrench perfectly for final tightening. The zinc plating seems evenly applied, no flaking or rough spots like cheaper screws I've gotten before. Exactly what I needed for a machinery guard panel.
