براغي ذات رأس سداسي 1/4-28 X 1" | فولاذ درجة 5 زنك أصفر | خيط كامل (300 / عبوة)

I needed a full box of 300 for a machinery repair, and the yellow zinc coating on these looks like it will hold up well against corrosion. They threaded smoothly into the tapped holes without any binding.

The yellow zinc coating is even and consistent across all 300 pieces, and the hex heads drive smoothly without stripping. I’ve been using them for jig assembly and they seat perfectly every time.

These bolts hold snug with a standard 1/4" drive socket, and the yellow zinc coating adds a nice layer of protection against rust on my shop equipment. The fully threaded length gave me solid grip through a thick bracket, and the pack of 300 means I won't need to reorder anytime soon.
