Evelyn F. ★★★★★

These screws are perfect for the outdoor gate hinges I’ve been fixing — the 18/8 stainless steel is holding up great after a few rainstorms. Even the slotted drive bit into the pre-drilled holes smoothly, no stripping.

Nicholas ★★★★★

Had to replace some corroded screws on an outdoor gate, and these 18/8 stainless ones fit perfectly. The slotted head drove in nice and easy with a standard screwdriver. Solid purchase for the price.

Brian ★★★★☆

The round head sits flush and looks clean on my project, and the 18/8 stainless steel gives me confidence they won't rust. The only small issue was that the slotted drive cammed out easily when I tried to torque them down tight.
