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.

Rivet Nuts for Sandwich Panels
To grip all layers of a sandwich panel—the top, core, and bottom—these rivet nuts have a two-piece construction. They combine a flanged rivet nut that grasps the top and a threaded insert that bonds to the core and bottom with adhesive. Use them to add strong, reusable threads so you can fasten your panel to other components. They won’t budge when you tighten a screw—between the adhesive and the rivet nut’s ribbed body, these nuts grip onto your material. The flange anchors the rivet nut so it doesn’t pull through, and it also helps distribute load from parts you fasten to the panel. Since these rivet nuts are made of 18-8 stainless steel, they stand up to mild chemicals and water.
Place the rivet nut into a drilled hole. Using a rivet nut tool, collapse the rivet nut against your panel to create a backside flange that holds it tight. With a mixing nozzle and dispensing gun, inject structural adhesive (all sold separately) through the rivet nut so the insert can stick to the bottom and core layer beneath. Add the reusable threads by threading the insert into the rivet nut with a slotted screwdriver. The closed end on the insert keeps the adhesive from leaking into the threads.

Flush-Mount Rivet Nuts
With an angled head, these rivet nuts sit flush in countersunk holes. Use them to create reusable threads in sheet metal and other surfaces that are too thin to be tapped. Installation requires access to just one side of your material. Made of steel, all have either a zinc or zinc yellow-chromate plating to resist corrosion in wet environments.
Install them in a drilled or punched countersunk hole with 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.
Tight-Spot Hex Head Screws
A high-strength alternative to blind rivets, use these screws when only one side of the material is accessible. To install, hold the washer in place with a wrench, and then use a hex socket to turn the screw. When the screw is tightened, the attached nut expands the sleeve to create a strong clamping force on the back of the material. Dimensions meet ISO 4017 (formerly DIN 933) specifications. Length is measured from under the head.

Lever-Style Rivet Nut Tools
Use two hands to maximize leverage when installing rivet nuts. These tools require a mandrel and nosepiece. To use, thread the nut onto the mandrel, insert the nut into a drilled hole, and squeeze the handles to secure the nut.
Tools with knob removal have a spin-to-reverse knob to quickly unthread the mandrel from the installed nut.

Single-Size Air-Powered Rivet Nut Tools
Use compressed air to install rivet nuts with less effort than manual tools. Tailored to specific thread sizes, these tools rotate a rivet nut with the exact force needed to collapse it onto your workpiece. They’re smaller and lighter than other powered rivet nut tools, so you can squeeze them into tighter spaces. However, they generate less force, so they’re not recommended for installing nuts into thick materials.

Air-Powered Rivet Nut Tools
Install any size or style of rivet nut with a single tool. When you connect these tools to your compressed air line, the hydraulic fluid inside is pressurized, which generates the force needed to collapse a rivet nut. They’re also known as hydropneumatic rivet nut tools. Rather than rotating the rivet nut, like single-size rivet nut tools, these tools pull it straight back. This means you can adjust the pull force or stroke depth to match your application. Set the pull force if you’re installing rivet nuts into workpieces with different thicknesses. Set the stroke depth to install rivet nuts in soft or fragile materials without cracking or warping the surface.
Use tools with a 7,190 lb. pulling force to install rivet nuts made from hard materials, such as titanium. They’re also good for large nut sizes. However, they take about three times longer to install a nut than tools with a 3,960 lb. pulling force.

Pull Force Calibrators for Rivet Nut Tools
Avoid failed rivet nuts by periodically testing the pull force of your rivet nut tool. These calibrators work with air-powered and hydraulic/air-powered rivet nut tools. They display force measurements on two digital touch screens. The left screen shows a graph and read-out of current pulling force, while the right screen shows the results of the last seven tests. Track performance to plan maintenance—they store test data on the included microSD card.
An anvil and mandrel assembly (sold separately) is required. Choose a thread size that matches your tool. Thread the anvil and mandrel assembly onto the calibrator to begin testing.
