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.

Stainless Steel Screw-Locking Aligning Press-Fit Nuts for Sheet Metal

Irregularly shaped threads in these press-fit nuts form a tight grip, preventing screws from backing out in vibration-heavy environments. Use these nuts to install corrosion-resistant threads that align with off-center parts. They have floating threads that account for misalignment, allowing you to insert screws at a slight angle as you fasten two parts together. With a long, extended barrel that’s threaded from end-to-end, these nuts have excellent thread engagement. They’re made of 18-8 stainless steel, so they stand up to mild chemicals and wet and outdoor environments.
Use press-fit nuts 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.
Nuts that meet NASM25027 adhere to National Aerospace Standards for tight tolerances and locking torque.

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.
18-8 stainless steel locknuts are more corrosion resistant than plated steel locknuts. They resist mild chemicals in addition to water.

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

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.

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.
