M3-0,5 x 18mm machineschroeven met platte kop en sleufaandrijving van 18/8 roestvast staal (800/stuk)

These screws are the perfect fit for my outdoor project, the flat head sits flush and the 18/8 stainless steel gives me confidence against rust. I’ve used cheaper packs before, but these threads cut cleanly without any stripping.

I needed a solid pack of stainless M3 screws for a marine project, and the 18/8 grade here is perfect—no rust after weeks of salt spray. The package of 800 gives me plenty for future repairs, though the slotted heads require a steady hand with a screwdriver.

Was surprised by how well these 18/8 stainless steel screws resist corrosion after a month outside in the rain. The flat heads sit perfectly flush in the mounting holes, and the slotted drive gives good control during installation.
