براغي هولو-كروم 60108 3/8-16 X 2" رأس أسطواني | محرك سداسي برأس مسطح | سبيكة فولاذية بأكسيد أسود حراري (50 / عبوة)

The black oxide finish on these screws is really uniform and looks great on my precision fixture. They threaded cleanly into tapped holes without any binding, which saved me time during assembly.

Used these to rebuild a couple of jigs in my shop and they seated perfectly flush, which is exactly what I needed for the flat head design. The 3/8-16 thread cut clean and the thermal black oxide has held up well against some light coolant splatter.

The black oxide finish is nice and uniform across all 50 screws, and the hex drive makes installation smooth without stripping. These worked perfectly for securing a heavy-duty jig I built for my shop.
