براغي تثبيت برأس أسطوانية بنقطة كوب M3 × 10 مم | فولاذ سبائكي مطلي بالزنك (1000 / عبوة)

The hex socket drive on these M3 screws made adjusting them in a tight spot much easier than I expected with standard Phillips. Pack of 1000 is more than enough for my small projects, and the zinc plating seems solid so far.

The cup point bites into the shaft way better than any flat-tip screw I've tried, and the hex socket makes cinching them down in tight spots a breeze. Zinc plating looks clean and none have stripped after a solid week of builds, so for a thousand pieces this is a steal.

I needed a bunch of M3 set screws for a 3D printer upgrade, and these alloy steel ones with the hex drive are exactly what I was after. The cup point grips the shaft really well without damaging it, and the zinc plating looks clean.
