HOLO-KROME 86023 براغي مقبس M5-0.8 X 25mm | محرك مقبس سداسي برأس زر | فولاذ سبائكي أكسيد أسود حراري (100 / عبوة)

Used a full bag mounting brackets for a CNC enclosure and every single one threaded smoothly without any binding. The 25mm length was exactly what I needed for these aluminum extrusions.

The black oxide finish on these is perfect for my tooling setup, gives them a nice grip feel without any galling. I've already used about 30 of them on a fixture and every single one threaded in clean with no defects.

I needed some decent M5 screws for a jig I was building, and these button heads fit perfectly in the counterbored holes. The black oxide finish looks clean and I haven't had any issues with the hex socket stripping.
