براغي رأس سداسية M3-0.5 × 16 مم | فولاذ مقاوم للصدأ 18/8 | ملولبة بالكامل (700/عبوة)

These are exactly the right size for my 3D printer frame and the fully threaded shank lets me use them as standoffs with a spacer nut. The 18/8 stainless finish looks clean and I didn’t find a single stripped or burred head in the whole 700 count.

Finally a hex head bolt that doesn’t strip the moment I tighten it—the 18/8 stainless takes a wrench well, and the fully threaded shaft holds my jig together without slipping. Four hundred of these in one box means I’m set for half a year of builds.

The threads are cut clean all the way down, so they grip perfectly even in shallow holes. I've used maybe 200 of these so far on a machine frame and not a single one has stripped or corroded.
