These little M2.5 screws fit perfectly into my 3D printer's hotend assembly, and the hex socket drive made installation a breeze without stripping. The zinc plating looks clean and consistent across all 600 pieces.

I needed exactly 600 M2.5 screws for a jig project, and these 16mm flat heads fit perfectly without stripping. The zinc plating looks clean and should resist rust in my shop.

Finally, a batch of 12.9 grade hardware where every single screw actually matches the spec—I checked a handful with a thread gauge and they're spot-on. The zinc plating has a nice, even finish with no burrs on the flats, which makes a real difference when you're seating them in tight jig holes.
