براغي رأس سداسية داخلية M2.5 × 8 مم | محرك سداسي داخلي | فولاذ سبائكي فئة 12.9 (900 / عبوة)

Used these for a jig I’m building and the hex socket drive made installation quick with no stripping. The alloy steel feels solid and the 900-pack will last through many projects.

Put together a custom jig for a small milling job and these screws threaded perfectly into tapped holes without binding. The 12.9 alloy steel gives me confidence they won’t strip under high torque.

I use these for my 3D printer’s linear rails, and the hex socket drive makes them easy to tighten without stripping. The 12.9 alloy steel feels much stronger than the standard screws I had before, and the 900-count pack will last me through many projects.
