براغي رأس سداسية 3/8-24 × 5/8 بوصة | فولاذ درجة 5 أصفر زنك | كاملة الخيوط (200 / عبوة)

The hex drive grabbed perfectly without any cam-out, and the yellow zinc coating gives them a nice, consistent look. These 200 pieces fit my equipment jig exactly as needed.

I needed some high-strength fasteners for a jig I’m building, and these grade 5 hex heads fit the bill perfectly—the yellow zinc coating is a nice touch for corrosion resistance. They thread smoothly into tapped holes without binding, and the full threading gives me solid grip in thin steel.

These bolts fit perfectly into the holes I drilled for mounting a small motor bracket. The yellow zinc coating looks good and the threading was clean all the way down without any burrs. A solid buy for the price.
