Customer Reviews (4.8 / 5 · 5 reviews)

Avery Q. ★★★★★

The slotted flat head sits flush and clean against my outdoor cabinet hinges, and the stainless steel finish hasn’t shown a speck of rust after a month in the rain. Perfect fit for those tight spots where you need a solid hold without the head sticking out.

Sofia ★★★★★

The 3-1/2" length is perfect for the washdown station I built—these held up through weeks of constant moisture without a hint of rust. The slotted heads seat nicely flush with a flathead driver, and being non-magnetic is a huge bonus when picking them up with a magnetic tray.

Lucy ★★★★★

I swapped out some regular steel screws for these 18/8 stainless ones on a fence gate that gets hosed down weekly, and after a month of rain there’s zero rust. The 3-1/2" length is perfect for the thicker wood I’m working with, and the flat heads sit flush without stripping.
