Using the Powers Fasteners PFM2511100 is a straightforward process. First, select the right spot on your concrete - filled metal deck for installation. Since the insert comes with pre - mounted self - drilling screws, you can quickly attach it to the deck. Make sure to use the recommended drill size of 7/16' or 1/2' for the best fit. The threaded bolt on the insert allows you to adjust its height to meet your specific requirements. Remember, the longer 'T' brace gives you more flexibility in choosing the installation location. When it comes to maintenance, keep the inserts clean and dry. As they are made of carbon steel, try to prevent them from being exposed to excessive moisture to avoid rusting. If you notice any damage or wear, it's a good idea to replace the insert right away. And always follow the safety guidelines during installation to ensure a successful and safe project.
