Ella L. ★★★★★

I was worried about finding matching screws for a stainless steel outdoor furniture project, but these 5/16-18 slotted heads worked perfectly and didn't rust after a week of rain. The rounded head sits flush against the metal without snagging, and the 2-1/2 inch length was just right for my thicker

Hannah ★★★★★

Needed a handful of these for a backyard gate hinge repair and the 18/8 stainless steel is holding up perfectly through the rain. The 2-1/2 inch length was exactly what I needed to secure the bracket.

Kevin B. ★★★★★

The slotted drive on these 2-1/2” machine screws makes them easy to torque down without stripping, and the 304 stainless finish has held up perfectly in my damp outdoor workbench.
