براغي مجموعة سوكيت بنقطة كوب M3 X 3mm | سبيكة فولاذ مطلية بالزنك (1000 / عبوة)

I was replacing some grub screws on a jig and these M3 x 3mm set screws threaded in much smoother than the old ones I had. The hex socket drive gave me a really solid grip for tightening them down securely.

The cup point tip really held tight without stripping when I was assembling a small jig. These M3 screws are perfect for tight spaces where a standard hex key just won’t fit.

The hex socket drive made it easy to tighten these M3 set screws into a tight spot on my 3D printer's extruder, and the cup point bit really grips the shaft firmly. A thousand pieces in the bag is way more than I'll need for this project, but it's nice to have spares.
