Julian A. ★★★★★

I needed a bunch of 3-inch stainless machine screws for a deck repair, and these 18/8 ones are holding up perfectly in the rain. They threaded into the pilot holes smoothly with no binding, and the Phillips heads didn’t strip on me at all.

Zoe ★★★★★

The Phillips heads seated cleanly without stripping on my workbench jig, which was a relief. These 3-inch lengths feel solid and the 18/8 stainless is exactly what I needed for a humid outdoor gate project.

Evelyn ★★★★★

Needed to replace some rusty bolts on my outdoor furniture, and these 3-inch stainless screws are a perfect fit—threaded smoothly and the fillister head sits flush. They’re non-magnetic too, which is a nice bonus for washdown areas.
