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.

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.

Wrench-Driven Rivet Nut Tools
Use these tools to install most styles of rivet nuts. A wrench and ratchet are required to hold the tool and tighten 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.

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.
