براغي تثبيت ذات رأس مقعر M3 X 10mm | سبائك فولاذية (1000 / عبوة)

Cup point tip seats perfectly flush in my aluminum project, and the alloy steel feels solid. Pack of a thousand is great for ongoing work.

The cup point tip bites into the shaft firmly, so there's zero wobble even after a full day of vibration on the machine. I've tightened them twice with a hex key and they haven't stripped at all. For a thousand pieces, that's solid value.

These set screws hold firmly thanks to the cup point tip, and the hex socket drive made installation in a tight spot a breeze. For the price, getting a full thousand pieces of alloy steel hardware feels like a solid deal.
