براغي رأس مقبس 3/4-10 × 16 بوصة | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي بأكسيد حراري أسود

I needed some heavy-duty screws for a jig I was building, and these 3/4-10 x 16" socket cap screws fit the bill perfectly. They’re partially threaded, which made alignment easy, and the black oxide finish looks durable and clean.

Used one of these to build a jig for my drill press, and the 16-inch length gave me just the right amount of thread engagement. The black oxide finish seems tough enough to resist a little oil and grime from the shop floor.

The hex socket drive made torquing these into my press frame much easier than I expected with a standard wrench. The black oxide finish slid into the threaded holes without any binding at all.
