Steel Heavy Duty Twist-Resistant Hex-Shaped Rivet Nuts
Our most twist-resistant rivet nuts, these hex nuts are held in place by their flat sides to keep them from spinning as you tighten screws. With thick walls that hold up in heavy duty applications, they're also among our strongest rivet nuts. Installation only requires access to one side of sheet metal. The flange distributes the load and secures these nuts to the surface of your material. Made of zinc-plated steel, they resist corrosion in wet environments.
Install in a hex-shaped punched hole with a hydraulic 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.

Screw-Locking Heavy Duty Twist-Resistant Rivet Nuts
Irregularly shaped threads in these nuts form a tight grip, preventing screws from backing out in vibration-heavy environments. Our most twist-resistant rivet nuts, these hex-shaped nuts are held in place by their flat sides to keep them from spinning as you tighten screws. They're also among our strongest rivet nuts and hold up in heavy duty applications. Use these rivet nuts to create reusable 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 these nuts against the surface. Made of zinc-plated steel, they resist corrosion in wet environments.
Install in a hex-shaped punched hole with a rivet nut tool. The tool collapses the nut, creating a backside flange that holds the nut to the material. Screw-locking threads require high torque for fastening and unfastening, so you may need an impact wrench to remove screws.
Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

Flange-Sealing Closed-End Rivet Nuts
With a durable plastic seal around a closed body, these rivet nuts add threads to sheet metal without letting water or dust pass through. They’re often used on surfaces that protect equipment, such as fuse box housings, in wet areas. They help maintain an enclosure’s IP68 rating for protection from water submersion and airborne dust. Made of 18-8 stainless steel, these rivet nuts withstand mild chemicals and resist corrosion in wet and outdoor environments.
Install these rivet nuts in sheet metal and other surfaces that are too thin to be tapped. Also known as blind inserts, installation requires access to just one side of your material. The flange distributes the load and holds these nuts against the surface. They collapse during installation, creating a backside flange that secures them to your material and creates a water-tight seal.
Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
Hex-body nuts are the most twist-resistant style of rivet nut. Their flat sides hold them in place, so they won’t turn as you tighten screws. Install them in a hex-shaped punched hole with a rivet nut tool.

Tools for Blind Rivets and Rivet Nuts
This tool has changeable nosepieces, anvils, and pull-up studs for installing rivets and rivet nuts. A self-contained hydraulic system delivers additional force to make installation easier. Choose the attachment that matches your rivet's diameter or nut thread size. To install a rivet, insert the mandrel into the nosepiece of the tool. Place the rivet in the material and squeeze the handles. The tool pulls the mandrel through the rivet's body, creating a secure hold on both sides of the material, and breaks off the excess mandrel.
Pull-up studs and driving anvils for 6-32 to 3/8"-16 and M3 to M10 rivet nuts are sold separately.
