M3-0.5 x 6mm 機械螺絲 | 圓頭一字槽 | 鋼鍍鋅 (3,300個/包)

These zinc-coated screws fit perfectly into my electronics enclosure and the slotted head let me tighten them down easily with a standard screwdriver. For the price, getting over three thousand pieces means I’ll never run out mid-project.

Got a whole bag of these M3 screws for a small electronics project and the consistent thread quality saved me a ton of frustration. The zinc coating also seems to hold up well on my outdoor sensor mount, no rust after a few weeks of rain.

These M3 screws are perfect for mounting PCBs in my projects, and the zinc plating on the steel gives me confidence they won't rust in the garage. 3,300 per package is way more than I'll ever need, but the price was right and they all look consistent.
