Mil. Spec. Rivet-Mount Nuts
Create threads in hard-to-work areas—where you can’t reach the back of a workpiece, or material is too thin to be tapped. For a strong grip, these nuts have distorted threads that increase friction with bolts. Because they mount with two rivets, they won’t spin when you’re tightening screws. However, these nuts do move inside their retainers, which lets you install bolts at a slight angle; use them to align with off-center parts. All meet military guidelines for dimensions and material.
Cadmium-plated nuts resist corrosion in industrial and saltwater environments, although will lose their corrosion resistance over 450° F. The cadmium plating also adds lubricity, making these nuts easy to install.
A286 stainless steel nuts are corrosion resistant. Silver-plated stainless steel nuts withstand temperatures up to 800° F. The silver plating also adds lubricity and prevents seizing caused by friction between nuts and bolts.
Lubricated nuts thread onto bolts smoothly.

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 strongest threads, choose steel nuts. Nuts with a steel retainer should be welded to uncoated steel surfaces. Zinc-plated steel nuts resist corrosion in wet environments. Nuts with an aluminum retainer should be welded to aluminum surfaces.
For the most corrosion resistance, choose stainless steel nuts. They have a stainless steel retainer, so they should be welded to stainless steel surfaces.

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.

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.
