براغي رأس سداسي M16-2 × 200 مم | فولاذ كلاس 10.5 مطلي بالزنك | ملولبة جزئيًا (10 / عبوة)

The partial threads grabbed perfectly on my equipment frame, and the hex heads seated cleanly with a standard socket wrench. Class 10.9 steel feels properly rigid, no flex during torquing. For the price per pack of ten, these are solid.

The partially threaded design made torquing these down on a conveyor frame much easier than fully threaded bolts. The zinc coating looks uniform and should resist rust in our shop environment.

Used these for mounting a motor mount on my lathe and the partial threading made alignment a breeze. The zinc plating looks clean and they cinched down tight without any stripping.
