Aligning Rivet Nuts
Threads float inside the nut so you can install a screw at a slight angle to align with off-center parts. They’re also known as Riv-Float nuts. A ribbed body makes them resistant to spinning and twisting. They're zinc plated for mild corrosion resistance. Install in a drilled hole with a wrench-driven tool (required, sold separately). Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

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.

Metric 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.
Weld steel nuts with a steel retainer to uncoated steel surfaces.

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.
