براغي رأس أسطوانية مقاس #8-32 × 2-7/8 بوصة | محرك سداسي | خيط جزئي | فولاذ سبائكي معالجة حرارياً بأكسيد أسود (100 / عبوة)

The black oxide finish on these screws looks sharp and gives them a nice grip in the wrench. The partial threading on the 2-7/8" length worked perfectly for my fixture setup, and all 100 came clean with no burrs or stripped heads.

Finally found the right length for an oddball bolt I needed for a machine jig — these #8-32 x 2-7/8" fit perfectly. The hex socket drive made installation a breeze, and the black oxide finish looks clean and professional.

The black oxide finish looks clean and professional on these #8-32 screws, and the hex socket drive made them easy to install in a tight spot on my milling fixture. My only minor knock is that the partial threading could be a bit longer for certain applications, but they work great overall.
