براغي رأس مقبس HOLO-KROME 86018 M5-0.8 × 15 مم | رأس زر مع محرك سداسي | فولاذ سبائكي مع أكسيد أسود حراري (100/عبوة)

Driving these into aluminum extrusion worked perfectly with a standard hex key, and the button head profile sits flush enough that my jig doesn’t catch. The thermal black oxide finish feels slick and uniform, so they thread in smoothly without any galling.

The black oxide coating on these screws gives them a nice, consistent finish that slides smoothly into M5 threads. Perfect for securing panels in a small CNC fixture I built.

The black oxide finish on these M5 bolts looks great and seems to resist rust well. They threaded into my jig perfectly with no binding, and the hex socket drive held tight.
