براغي رأس أسطواني 3/4-10 X 5-1/2" | محرك سداسي | صنع في الولايات المتحدة | فولاذ سبائكي بأكسيد أسود حراري (35 / عبوة)

Needed a solid batch for a heavy jig I'm building, and these 3/4-10s threaded clean without any galling. The thermal black oxide looks even and gave a nice, consistent finish across all 35 pieces. They seat firmly with a hex key, so I'm confident they'll hold up under load.

I needed some heavy-duty bolts for a jig I'm building, and these 5-1/2" long screws gave me the exact thread engagement I was looking for. The hex socket drive made installation a breeze with my allen wrench.

The black oxide finish is a nice touch—it gives them a clean, uniform look and seems to resist handling marks better than plain steel. I’ve been using them to bolt down a heavy jig base, and the threads cut easily without any binding. For the price per package, you’re getting solid USA-made hardware
