Steel Rivet Nuts
Add strong threads to sheet metal and other thin surfaces. Zinc plating protects these rivet nuts from degrading in wet environments. They’re also known as blind inserts—installation requires access to just one side of your material. Install them in a drilled or punched round hole using a rivet nut tool. The tool collapses the nut, creating a backside flange that holds the nut to the material.
Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

Steel Low-Profile Rivet Nuts
These steel low-profile rivet nuts are about twice as strong as aluminum rivet nuts. They have a low profile for light duty fastening in low-clearance applications. A cadmium or tin-zinc plating provides corrosion resistance and adds lubricity so they collapse smoothly. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut. Drill bit size listed in the table is for material with a 0.030"-0.090" thickness. These rivet nuts may be installed in thicker material, but may require larger holes. Install them using a hand- or power-driven rivet nut tool. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

Steel Low-Profile Rivet Nuts with Installation Tool
Everything you need to add threads to sheet metal in low-clearance areas. Along with low-profile rivet nuts, these kits include mandrels and an installation tool. As you install these nuts, the threaded portion is drawn into the sleeve, reducing how far they stick out the back of your material. They also have a flange that’s half as thick as those on other rivet nuts, so they have a low profile on both sides of your panel. A tin-zinc plating protects from rust in wet environments and reduces friction, so they collapse smoothly. These rivet nuts create permanent threads in surfaces that are too thin to be tapped. Installation requires access to just one side of your material. The flange distributes the load and holds them against the surface.
To install, thread a rivet nut onto the mandrel, insert the nut into a drilled or punched round hole, push down on the tool's T-handle, and turn clockwise.

Stainless Steel Low-Profile Rivet Nuts
The most corrosion resistant low-profile rivet nuts we offer, these stand up to chemicals. They're often used for light duty fastening in low-clearance applications. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut. The tin-plating provides lubricity allowing the nut to collapse smoothly. Drill bit size listed in the table is for material with a 0.030"-0.090" thickness. These rivet nuts can be installed in thicker material, but may require larger holes. Install them using a hand- or power-driven rivet nut tool. Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

Aluminum Low-Profile Rivet Nuts
These low-profile rivet nuts are one-third the weight of steel rivet nuts. They have a low profile for light duty fastening in low-clearance applications. A cadmium or tin-zinc plating provides corrosion resistance and adds lubricity so they collapse smoothly. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut. Drill bit size listed in the table is for material with a 0.030"-0.090" thickness. These rivet nuts may be installed in thicker material, but may require larger holes. Install them using a hand- or power-driven rivet nut tool. 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.

Low-Profile Rivet Nut Assortments
Use these rivet nuts for light duty fastening in low-clearance applications. Assortments include rivet nuts, mandrels, and an installation tool. Rivet nuts have a cadmium plating that provides corrosion resistance and adds lubricity so they collapse smoothly. The threaded portion is drawn into the sleeve when installed, creating pressure against the hole to secure the nut.

Air-Powered Rivet Nut Tools
Smaller and lighter than cordless and hydraulic rivet nut tools, use these to install thin-walled bulbed, ribbed, sleeve, and smooth rivet nuts. To use, thread the nut onto the included mandrel and press the trigger to spin the nut onto the tool. Place the nut into the material and press the trigger to install the nut. Press the trigger one more time to spin the mandrel off.
