Eva ★★★★★

Cheese head on these M3 screws really grabs the slotted driver nicely, no slipping when I’m tightening them down. The 20mm length is perfect for the small electronics bracket I was mounting.

Hazel B. ★★★★★

I've been using these screws for a few small electronics enclosures and the slotted head lets me get a good bite with a standard flathead driver. The zinc coating feels sturdy enough for the light outdoor use I need them for.

Sophia ★★★★★

These M3 screws are consistently threaded, making assembly smooth without any binding. I like that the zinc plating adds a bit of corrosion protection for the price. A solid value for 2,100 pieces.
