براغي رأس سداسي ثقيلة 1/2-13 × 2-1/2 بوصة | صناعة أمريكية | فولاذ A307 درجة B مطلي بالزنك | ملولبة جزئيًا (225 / عبوة)

The zinc coating on these hex cap screws is nice and even, and the 225 count per package is exactly what I needed for a large machine assembly project.

The partially threaded design made these hex bolts grip perfectly on my heavy equipment frame without any slip. They seated flush with the nut driver and the zinc coating looks clean and solid. Exactly what I needed for industrial assembly work.

Needed to replace some worn bolts on an industrial press and these heavy hex heads fit perfectly. The zinc plating looks consistent and the partial threading made installation a breeze.
