هولو-كروم 76012 براغي رأس مقبس M3-0.5 × 8 مم | محرك مقبس سداسي | فولاذ سبائكي بأكسيد حراري أسود (100 / عبوة)

Finally a small screw that actually feels sturdy and precise in hand. The hex socket drive fits perfectly in my tooling jig without any wobble. I've already ordered another pack for my next project.

The thermal black oxide finish on these M3 screws seems to give them a nice grip during assembly, and they fit perfectly into my 3D printer's precision jigs. Definitely solid for tooling work.

I was pleasantly surprised by the consistent black oxide finish across all 100 screws—no bare spots or uneven coloring. They threaded smoothly into my 3D printer's aluminum frame without any binding.
