براغي رأس سداسي مقاس 1/2-20 × 3-1/2 بوصة | فولاذ درجة 5 بطلاء زنك أصفر | ملولبة جزئياً (25 / عبوة)

The threads are clean and the hex head fits a standard wrench perfectly, making these bolts feel solid for heavy equipment use. I used them to secure a jig on my milling machine, and the partial threading made alignment much easier. Really happy with the quality for the price.

I needed some partially threaded bolts for a machinery repair and these 1/2-20 x 3-1/2" cap screws fit perfectly. The hex head made them easy to drive with a socket, and the Grade 5 steel feels solid.

The yellow zinc coating on these hex head bolts is nice and even, making them easy to grip with a wrench. They fit perfectly into my existing equipment assembly without any binding. Exactly what I needed for a solid, reliable hold.
