براغي رأس سداسية M16-1.5 × 120 مم | فولاذ فئة 10.9 مطلي بالزنك | ملولبة بالكامل (80 / عبوة)

The threads are cut clean and the zinc plating is uniform across all 80 pieces, so they should hold up fine in our shop environment. I used them to bolt down a heavy motor mount and the Class 10.9 strength gave me plenty of confidence torquing them to spec without worrying about stripping.

Pulling these out of the package, the consistent 1.5mm thread pitch on every bolt makes alignment effortless when fitting flanges. The zinc plating has held up well even after getting a bit of moisture on them during a motor mount job, no rust starting yet.

The threads are clean and uniform across all 80 pieces, and the zinc plating looks consistent with no flaking. I torqued them to spec on a conveyor frame and the hex heads seated perfectly without stripping.
