Steel Press-Fit Nuts with Plug for Sheet Metal
A plug on these press-fit nuts protects the threads inside during painting and other finishing processes. Made of rubber, the plug withstands high-temperature treatments such as curing during powder coating. These press-fit nuts add permanent threads to thin metal surfaces, like weld nuts but without the setup and mess. Also known as clinch-style captive nuts, press them into a drilled or punched hole 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. Installation requires access to both sides of the panel. When you are ready to use the threads, push the plug through the nut with a tool like a screwdriver.

Thread-Shielding Tee Nut Inserts
Create strong threads in wood and plastic that won’t get clogged with paint or debris. These tee nut inserts have a protective plug on the bottom to block out substances during finishing processes. Four prongs on the flange grip the surrounding material to help prevent twisting. Made of 18-8 stainless steel, these inserts resist corrosion better than zinc-plated steel inserts.
To install these inserts in plastic parts, you'll need to include them in your injection molding process. Made of silicone, which is highly resistant to heat, the plug won’t melt during molding. Install these plugs in wood at any time—just hammer them into a drilled hole. Once you’ve installed an insert and completed any finishing processes, the plug is easy to remove. You can either pop it out by threading your fastener through the insert or just peel it off with your finger.
Note: The installed length includes the flange.
