Stainless Steel Heavy Duty Twist-Resistant Hex-Shaped Rivet Nuts

Ideal for wet and outdoor environments, these rivet nuts are made of stainless steel. Their hex-shaped body provides the highest twist resistance of any rivet nut. As you tighten screws, the flat sides hold them in place to keep them from spinning. They hold up in heavy duty applications because of their thick walls, making them some of our strongest rivet nuts. To install them, you only need access to one side of your sheet metal. The flange distributes the load and secures these nuts to the surface of your material.
Install them 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.
Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.
316 stainless steel nuts have excellent corrosion resistance. They stand up to salt water and harsh chemicals.

Stainless Steel Rivet Nuts
Made of stainless steel, these rivet nuts hold up better outdoors than zinc-plated steel rivet nuts. Use them to add corrosion-resistant threads to surfaces that are too thin to be tapped, such as sheet metal. Also known as blind inserts, they require access to just one side of your material for installation. The flange distributes the load and secures these nuts to the surface 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 also holds them to the material.
Length is measured from under the flange. Installed length is the maximum length of the barrel when installed.

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.
