M3 x 10粗螺紋圓頭螺絲 - 10入

The coarse threads bite into plastic way better than standard M3 screws I've used before. I was worried 10mm might be too long for my enclosure, but they seated perfectly. Ten in a pack is plenty for a small project.

Used these to secure a small board into 3D-printed standoffs, and the coarse pitch grabs the plastic firmly without any tap. The button head profile gives plenty of room in a tight assembly. Ten pieces is a handy little stash for future projects.

The coarse threads bite into ABS prints way better than the fine-thread M3s I had lying around, and the button heads sit almost flush. Ten in a pack was just enough for my enclosure project.
