براغي ماكينة M2-0.4 × 20 مم | رأس مقلاة مع شق فيليبس | فولاذ مطلي بالزنك (3,600 / عبوة)

The zinc coating on these M2 screws gives me confidence they won't rust on my outdoor sensor housing, and the 20mm length is perfect for securing plastic brackets. I used about 200 so far and every single one threaded smoothly without stripping.

Bought these for a small electronics bracket job and the 20mm length was exactly right—the pan head sits flush enough for tight spots. The zinc coating has held up fine in my garage, no spotting after a couple humid weeks.

Finally, a machine screw pack that actually includes enough for the job — 3,600 pieces is no joke. The zinc coating feels decently smooth and should hold up fine inside a shed or garage project.
