براغي رأس أسطوانية 7/8-9 × 10" | رأس مسطحة بمحرك سداسي | فولاذ سبائكي بأكسيد أسود حراري (5 / عبوة)

These 10-inch-long screws were perfect for a deep jig assembly I was building—the thread engagement felt solid and precise. The black oxide coating looks clean and seems like it'll resist rust well in my shop. Exactly what I needed for this fixture project.

The hex socket drive gripped my Allen wrench perfectly without stripping, and the black oxide finish has held up well against rust in my jig setup. For ten-inch screws this precise, the five-pack price is a solid deal. I've already ordered more for my next tooling project.

The thermal black oxide finish took the machining marks right out of the look, and the hex socket drive seated my allen wrench with zero wobble. These 10-inchers held a heavy fixture steady all afternoon without a hint of flex. Exactly what my tooling cabinet needed.
