براغي رأس سداسية 1/2-13 × 4 بوصة | فولاذ درجة 8 مطلي بالزنك | ملولبة جزئيًا (150 / عبوة)

These 1/2-13 x 4" hex head screws are exactly what I needed for a heavy equipment repair. The partially threaded shaft made installation easy, and the hex heads hold tight without stripping. A solid, reliable fastener pack for tough jobs.

The zinc plating on these bolts is holding up well even after a few days in damp conditions. They threaded smoothly into my heavy equipment mount with no binding. Exactly the consistent Grade 8 quality I was hoping for.

The hex heads have a nice clean profile that my socket wrench grabs perfectly, and the zinc coating looks durable for outdoor machinery use. These feel much more solid than the cheap hardware store bolts I usually get stuck with.
