M2-0.4 X 20mm 機械螺絲 | 圓頭一字槽驅動 | 鍍鋅鋼（2,700入/包）

Packed 2,700 screws in one bag saves me a trip to the hardware store mid-project, and the zinc coating on these M2-0.4 x 20mm cheese heads looks even and will handle light outdoor use well.

Slotted cheese head drives are getting harder to find, so grabbing a full 2,700-pack of these zinc-plated M2s felt like a small win. They seat cleanly with a standard screwdriver and the plating looks uniform across the batch, which matters when you’re using them on visible hardware.

The 20mm length was exactly what I needed for mounting a circuit board in a small project box, and the zinc coating gave them a nice, uniform finish right out of the bag. Slotted drive works fine with a standard screwdriver, and at 2,700 pieces, I won't be running out anytime soon.
