HOLO-KROME 72112 1/4-20 × 2-1/2 بوصة براغي رأس كبس | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراري (100 / عبوة)

Pulled these out of the package and the black oxide finish is even and clean, no burrs on the threads. They seated perfectly in my milling machine’s T-slots.

I needed some strong fasteners for a jig I was building, and these 1/4-20 x 2-1/2" cap screws fit the bill perfectly—they drove in smoothly with my hex key and the thermal black oxide finish looks great for resisting wear.

The black oxide finish on these screws is flawless, and the hex socket drive gripped my driver bit without any slipping. I used them to re-secure a machine guard and they threaded in perfectly, no burrs or rough edges on the threads.
