براغي رأس سداسي 1/2-20 × 6 بوصة | فولاذ درجة 5 مطلي بالزنك الأصفر | ملولبة جزئياً (25 / عبوة)

The partially threaded design made it easy to tighten down without binding up, and the yellow zinc coating looks better than the plain steel ones I've used before. These bolts feel solid for heavy equipment assembly.

Needed to replace some hardware on an old press, and these grade 5 bolts handled the torque without any issue. The yellow zinc finish matched the existing parts perfectly and still looks clean after a few weeks.

These bolts threaded smoothly into my milling machine table, and the zinc coating seems thick enough to resist rust. I needed these for a heavy repair and the partial threading gave just the right hold.
