HOLO-KROME 76160 مسامير رأس مقبس M6-1 X 12mm، محرك سداسي، فولاذ سبائكي، أكسيد أسود حراري (100/عبوة)

The black oxide finish on these screws looks clean and professional, and they threaded into my tooling fixture without any binding. Perfect for precision assemblies where you need consistent fit.

I needed some sturdy fasteners for a jig build, and these M6s came through perfectly—the hex socket drive made tightening them a breeze even in tight spots. The thermal black oxide finish also looks great and hasn't shown any wear so far.

The black oxide finish on these screws adds a nice layer of corrosion resistance, and the hex socket drive made tightening them in my tooling jig much easier than with a standard slot. The 12mm length was exactly what I needed for this assembly.
