HOLO-KROME 60070 1/4-20 X 1-3/4" براغي ذات رأس مقبس | محرك سداسي مسطح الرأس | فولاذ سبائكي مؤكسد أسود حراري (100 / عبوة)

The flat head sits perfectly flush in my jig plate, and the thermal black oxide finish has held up great without any rust after a few weeks of machine use. Thread engagement on these 1/4-20s feels precise every time I drive one in, and a hundred pieces in one box is a solid deal.

I’ve been using these in my tooling fixtures and the black oxide finish holds up well against oil and chips. The flat head sits flush perfectly, which made assembly much cleaner.

Perfect fit for the jig I built—the black oxide finish on these screws is nice and consistent, and they threaded smoothly into tapped holes without any binding.
