Customer Reviews

Emily Davis

For my outdoor deck build, I needed durable wood screws. These from Zhongsheng Hardware didn’t disappoint—they’re corrosion-resistant, and after months of rain, there’s no sign of rust. The screws fit perfectly with my decking boards, and their strength ensures the deck stays secure. The packaging kept them dry during storage, and the professional team even helped me pick the right length. Great product for outdoor use!

Michael Brown

I used these wood screws to fix my old dining table, and they worked wonderfully. The screws are sturdy, and their smooth surface didn’t damage the table’s wood finish. They’re easy to install with a regular screwdriver, and they’ve held the table legs firmly in place for weeks. The assortment of sizes in the PVC Blister box was convenient, as I needed different lengths for various parts. Worth every penny!
