The black oxide finish on these screws is flawless—no chips or uneven spots across all 25 pieces. I used them to secure a heavy-duty jig plate and the 3/4-16 threads seated perfectly with zero binding.

Used a full box of these for a heavy-duty jig on a press, and the socket drive made installation a breeze. The black oxide finish looks flawless and hasn't chipped at all after torquing down hard.

The black oxide finish on these screws gave them a nice, uniform look once installed in my tooling fixture, and they seated perfectly with a hex key. No stripped heads or fussing, exactly what I needed for a precision assembly.
