براغي رأس سداسية 1/4-20 × 1 بوصة | فولاذ درجة 5 زنك أصفر | ملولبة بالكامل (2200/عبوة)

These bolts fit perfectly in my assembly jig, and the yellow zinc coating gives them a nice consistent finish that doesn't flake off during tightening. For a bulk pack, the threads were clean and started easily in every nut I tried.

I needed a bulk order for a machine rebuild, and these hex heads threaded smoothly into tapped holes without any binding. The Grade 5 steel feels solid, and the 2200-count package lasted through my whole project with some to spare.

The yellow zinc coating is evenly applied and the threads are clean on every single one I’ve checked so far. They drive in smoothly with a socket, and having the full 2200 in one box saved me a trip to the hardware store.
