براغي رأس سداسية مقاس 3/4-16 × 5-1/2 بوصة | فولاذ درجة 5 بزنك أصفر | ملولبة جزئيًا (25 / عبوة)

The threads cut clean and the yellow zinc finish looks uniform across all 25 pieces. Used them to bolt down a press frame and the partial threads let me snug everything up without binding.

I needed these for a heavy machinery repair and the hex head gave my socket wrench a solid grip without stripping. The yellow zinc coating looks good and should hold up against moisture in the shop.

The yellow zinc coating on these is really well done, looks even and smooth. The partial threading made them much easier to start by hand when I was mounting a heavy bracket. These definitely feel tougher than the standard hardware store bolts I've used before.
