Matthew J. ★★★★★

The slotted heads bite the screwdriver nicely without camming out, even when I'm torquing them into tight spots. These 18/8 screws don't show a hint of rust after a week of outdoor rain, and the 100-count box is plenty for my project.

Michael N. ★★★★★

The slotted drive on these 3/8-16 screws caught a standard flathead just fine, and the 304 stainless feels solid for outdoor projects. I've already used a handful on a gate hinge rebuild with no rust issues.

Isabella ★★★★★

I replaced a bunch of ordinary screws on my patio furniture with these 18/8 stainless ones, and they're holding up perfectly in the rain. The slotted drive head makes them easy to seat with a standard screwdriver.
