Thanks to their covered threads, these press-fit nuts protect against leaks and debris. They have a zinc plating to prevent them from rusting in wet environments. Use them to add permanent threads to sheet metal and panels without the setup and mess of weld nuts. For installation, make sure you have access to both sides of your workpiece. Line them up with a drilled or punched hole that suits their size, then press them down with an arbor press or similar pressure tool. The pressure forms your sheet metal into the knurls of the nut, making the nut inseparable from the sheet. Also known as clinch-style captive nuts.
