براغي رأس كبسولة HOLO-KROME 76170 M6-1 × 18mm | محرك سداسي | فولاذ سبائكي مع أكسيد أسود حراري (100 / عبوة)

These little screws fit perfectly into the precision assembly I was working on, and the black oxide coating gives them a nice, consistent finish. I've used a handful so far and they tighten down smoothly without any stripping.

I used these M6 socket cap screws for a jig I was building, and they seated perfectly with no wobble. The hex socket drive made tightening them in tight spots much easier than a regular bolt.

The black oxide finish on these M6 screws looks clean and provides a bit of corrosion resistance for my jig setup. Used them to mount a small fixture, and the hex socket drive made installation easy without stripping.
