The hex socket drive is perfectly machined on these, so my 1.5mm Allen key grips every single one without slipping. They're holding up great in the jig I built, and the zinc plating looks uniform across all 400 pieces.

I was a bit skeptical about such tiny screws holding my jig together, but these threaded smoothly into the pre-tapped holes and haven't budged since. The zinc plating looks clean and rust-free even after a few weeks in my damp garage.

These little screws threaded perfectly into my precision assembly jig without any cross-threading. The hex socket drive made installation much easier than a Phillips head would have been.
