براغي رأس كبس 1-3/4-5 × 5 بوصة | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي أكسيد أسود حراري

I was replacing some worn jig hardware and the fully threaded length on these 1-3/4-5 screws made alignment much easier. The black oxide finish seems like it'll hold up well against shop grime too.

The hex socket drive on these screws gripped my driver bit perfectly with zero slipping, even when I torqued them down in a steel jig. The full threading along the 5-inch length made alignment a breeze during assembly.

The black oxide finish on these screws looks really clean and seems like it'll resist rust well in my shop environment. They threaded smoothly into the tapped holes on my precision assembly jig without any binding.
