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.

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.

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.
Smooth-body nuts can be installed in either a drilled or punched hole using a rivet nut tool.
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.

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.
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.
