Metric Steel Press-Fit Nuts for Sheet Metal
Add permanent metric threads to sheet metal, like weld nuts, but without the setup and mess. A zinc plating on these steel press-fit nuts provides corrosion resistance in wet environments. 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.

Stainless Steel Narrow Press-Fit Nuts for Sheet Metal
15% narrower than other press-fit nuts, these add corrosion-resistant threads to sheet metal in tight spaces. Made of stainless steel, these press-fit nuts withstand water and chemicals better than zinc-plated steel nuts. They 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.

Aluminum Press-Fit Nuts for Sheet Metal
Add lightweight, corrosion-resistant threads to sheet metal. These aluminum press-fit nuts are one-third the weight of steel press-fit nuts and better withstand wet environments. However, they’re only about half as strong. Use press-fit nuts to 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.

Stainless Steel Aligning Press-Fit Nuts for Sheet Metal
Install corrosion-resistant threads that align with off-center parts. These press-fit nuts have floating threads that account for misalignment, allowing you to insert screws at a slight angle as you fasten two parts together. Made of 18-8 stainless steel, they withstand mild chemicals and can be used in wet and outdoor environments. Use them to add permanent threads to sheet metal, 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.

Nylon-Insert Press-Fit Locknuts for Sheet Metal
A nylon insert in these press-fit locknuts grips threads to prevent screws from loosening while knurls on the bottom hold these locknuts firmly in place. Use these locknuts to add permanent threads to sheet metal, similar to 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 installation tool. The pressure forms your sheet metal into the knurls of the locknut, making the locknut inseparable from the sheet. Installation requires access to both sides of the panel.

Steel Thread-Sealing Closed-End Press-Fit Nuts for Sheet Metal
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.

Metric Stainless Steel Press-Fit Nuts for Soft Metal and Plastic
Add permanent metric threads that resist corrosion to a panel. These nuts are 18-8 stainless steel, so they withstand exposure to mild chemicals and water better than zinc-plated steel nuts. Also known as broach-style captive nuts, they work similarly to weld nuts but without the mess. Press them into a drilled or punched hole using an arbor press or similar pressure tool. The pressure forces the panel into the knurls of the nut, keeping the nut firmly in place. Installation requires access to both sides of the panel.
