Finally a tiny screw that threads smoothly into my RC car's servo horn without stripping. The black oxide finish also resists the little bit of oil I use, which is a nice bonus.

I needed a reliable fastener for a small jig I'm building, and the black oxide finish on these M1.6 screws gives them a nice, non-reflective look while holding tight. The hex socket drive makes installation with a tiny driver effortless, even in tight spots.

These tiny M1.6 screws are perfectly machined for my precision jig builds — the hex socket drive grips the driver snugly, no stripping. The black oxide finish looks uniform and clean across all 600 pieces.
