براغي رأس أسطوانية M3-0.5 X 25mm | محرك سداسي داخلي | سنون جزئية | فولاذ سبائكي فئة 12.9 مطلي بالزنك (600/عبوة)

I was replacing some worn-out screws on a custom jig, and these M3s fit perfectly with no wobble. The partially threaded design made alignment much easier than fully threaded options I've used before. The zinc plating looks sturdy and should hold up well in my workshop.

The hex socket drive seats perfectly on my Allen key, and the zinc plating looks clean and uniform across all 600 pieces. Threading them into my precision assembly was smooth with no binding or stripped heads.

Needed a batch of solid M3 screws for a jig I'm building, and these 12.9 alloy steel cap screws are tough—the hex drive bit seated perfectly without stripping. They came in a pack of 600, which is more than enough for my shop projects.
