براغي ماكينة M4-0.7 × 30 مم | رأس جبنة مشقوقة | فولاذ مقاوم للصدأ 18/8 (400 / عبوة)

Corrosion resistance was my main worry for an outdoor project, but these 18/8 screws have held up perfectly through a couple of rainy weeks already. The slotted drive is easy to seat, and the cheese head sits flush without stripping.

I needed some longer M4 screws for a washdown station project and these 30mm ones did the trick. The 18/8 stainless feels solid and the cheese head gives a good grip for the slotted driver. No rust after a few weeks in a damp environment.

The slotted drive on these M4 screws is a nice change from Phillips—my screwdriver stays seated without camming out. I’m using them for an outdoor birdhouse project, and the 18/8 stainless steel gives me confidence they won’t rust. The full 400-count pack should last me a while.
