To protect against leaks and debris, these press-fit nuts have enclosed threads. Their 18-8 stainless steel construction resists corrosion from mild chemicals and water better than zinc-plated steel nuts. 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 push them down with an arbor press or similar pressure tool. Once the pressure melds the knurls of these nuts with the material, they’re inseparable. Also known as clinch-style captive nuts.
