Steel Twist-Resistant Rivet Nuts
Made of steel, these rivet nuts add strong, reusable threads to sheet metal and other material that’s too thin to tap. Their ribbed body grips material better than smooth-body rivet nuts, so they won't twist when you tighten a screw. Also known as blind inserts, they can be installed when you have access to only one side of the material. With a zinc yellow-chromate plating, these nuts resist corrosion in wet environments.
Install these nuts 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.

Stainless Steel Twist-Resistant Rivet Nuts
Made of 18-8 stainless steel, these rivet nuts withstand water, mild chemicals, and outdoor conditions better than zinc-plated steel nuts. A ribbed body grips surrounding material to hold them in place, keeping them from spinning as you tighten screws. Rivet nuts create permanent threads in sheet metal and other surfaces that are too thin to be tapped. They’re also known as blind inserts—installation requires access to just one side of your material. The flange distributes the load and holds them against the surface.
Secure them in a drilled or punched round hole with a wrench- or power-driven 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.

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.
