Stainless Steel Press-Fit Nuts for Sheet Metal
Create permanent, corrosion-resistant threads in sheet metal without the setup and mess of weld nuts. Made of 18-8 stainless steel, these press-fit nuts withstand water and mild chemicals better than zinc-plated steel nuts. 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.

Metric Stainless Steel Press-Fit Nuts for Sheet Metal
Made from 18-8 stainless steel, these metric nuts withstand contact with water and chemicals better than zinc-plated steel nuts. They 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. 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.

Flush-Mount Press-Fit Nuts for Sheet Metal
To fit in low-clearance areas, these press-fit nuts have a flat hex head that sits flush against the surface of your material. Made of 18-8 stainless steel, they withstand contact with water and chemicals better than zinc-plated steel nuts. 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. 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. 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.

Nylon-Insert Press-Fit Locknuts for Sheet Metal
These press-fit nuts have a nylon insert that grips threads to resist loosening and knurls on the bottom of the nut that hold them firmly in place. Press them into a drilled or punched hole with an installation tool or an arbor press. Installation requires access to both sides of the panel.
18-8 stainless steel locknuts are chemical resistant and may be mildly magnetic.

Stainless Steel Press-Fit Nuts for Soft Metal and Plastic
Create corrosion-resistant threads in soft metal and plastic panels—these stainless steel press-fit nuts withstand exposure to water and chemicals. Also known as broach-style captive nuts, they add permanent threads to sheets, like weld nuts, but without the setup and mess. Press them into a drilled or punched hole with an arbor press or similar pressure tool. The pressure forms your material into the knurls of the nut, making the nut inseparable from the sheet. Installation requires access to both sides of the panel.

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.

Stainless Steel Snap-In Nuts
These nuts have good chemical resistance and may be mildly magnetic. Snap them into square holes in thin material. Threads float inside the retainer so you can install a bolt at a slight angle to align with off-center parts. Mounting legs expand to lock the fastener in place. They can be installed by hand or with pliers.

Aligning Weld Nuts
Threads float inside the retainer so you can install a bolt at a slight angle to align with off-center parts. Weld these nuts to metal surfaces for a strong, permanent hold. They stand up to high torque and pulling force better than rivet nuts.
For the most corrosion resistance, choose stainless steel nuts. They have a stainless steel retainer, so they should be welded to stainless steel surfaces.
