Timothy ★★★★★

Phillips drive seated perfectly on these, and the integrated washer really saved me time on a small assembly project. The 18-8 stainless feels solid and corrosion-resistant for outdoor use.

Michael ★★★★★

I needed stainless hardware that wouldn't rust in a damp shop, and these 18-8 sem screws fit the bill perfectly—the built-in external tooth lock washer saved me from having to grab separate washers. They thread smoothly into pre-tapped holes and the phillips drive doesn't cam out easily.

David ★★★★★

The pan head sits flush against the work surface without any wobble, and the external teeth really bite into the metal plate I was fastening. I’ve used cheaper stainless screws that stripped easily, but these 18-8 ones held up through all 100 pieces without a single issue.
