براغي ذات رأس أسطواني 5/8-11 × 6 بوصة | محرك سداسي | صنع في الولايات المتحدة | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

The black oxide finish on these screws is really smooth and uniform, making them look great on my jig build. The hex socket drive grabbed perfectly with my Allen key, and they threaded in without any binding. Exactly the heavy-duty hold I needed for this machinery setup.

Used these to replace worn bolts on a milling fixture and the threads cut cleanly into tapped holes without any binding. The 5/8-11 size matched up perfectly for my tooling setup.

The black oxide finish on these is flawless, no rough edges or flaking when I torqued them into my fixture. The hex socket grabbed perfectly with my Allen key, and all 100 threads were clean and uniform straight out of the box.
