These expansion anchors seem to be heavy-duty and perfect for securing items to concrete. I am using them to secure a railing. The set comes with multiple lengths, which is super convenient for different projects. Rock solid. Easy to install with the right tools and made from quality zinc. Great set for anyone working with cement or masonry!
