براغي ذات رأس سداسي ثقيل 5/8-11 × 2-1/4 بوصة | صناعة أمريكية | فولاذ A307 درجة B مطلي بالزنك | ملولبة جزئيًا (150 / عبوة)

Grip is excellent on these bolts—the threading is clean and consistent, and the zinc finish feels durable. They fit perfectly in my press frame without any wobble.

Used these on a heavy-duty trailer hitch project and the partially threaded design made alignment much easier. The zinc coating handled a few days in the rain before I got everything torqued down, no rust yet.

Zinc plating looks uniform and the threads are clean, so they drove in smoothly when I used them to bolt a steel bracket to a concrete form. The 2-1/4" partial thread gave just enough grip without bottoming out.
