About Nuts, Materials, and Finishes

Steel Twist-Resistant Rivet Nuts

About twice as strong as aluminum rivet nuts, these steel rivet nuts are zinc plated for mild corrosion resistance.

Stainless Steel Twist-Resistant Rivet Nuts

The most corrosion resistant twist-resistant rivet nuts we offer, these stand up to chemicals.

Aluminum Twist-Resistant Rivet Nuts

These aluminum rivet nuts are one-third the weight of steel rivet nuts and have mild corrosion resistance.

Heavy Duty Twist-Resistant Rivet Nuts

A hex-shaped body provides the highest twist resistance of any rivet nut.

Steel Low-Profile Rivet Nuts

About twice as strong as aluminum rivet nuts, these low-profile rivet nuts have a cadmium or tin-zinc plating for corrosion resistance.

Stainless Steel Low-Profile Rivet Nuts

The most corrosion resistant low-profile rivet nuts we offer, these stand up to chemicals.

Aluminum Low-Profile Rivet Nuts

These low-profile rivet nuts are one-third the weight of steel and have mild corrosion resistance.

Rivet Nuts for Plastic and Composites

Once installed these rivet nuts have a large back flange that distributes the load across a broad area for a strong hold in plastic and composites.

Thread-Sealing Closed-End Rivet Nuts

The thread area is enclosed, which prevents leakage past the threads from either side of your application.

Flange-Sealing Rivet Nuts

A PVC foam seal under the flange keeps liquids and gasses from leaking between the nut and the surrounding material.

Screw-to-Install Rivet Nuts

These rivet nuts are mildly corrosion resistant.

Insulating Rivet Nuts

A nonconductive rubber coating insulates the nut from electricity, seals out moisture, and damps vibration.

Aligning Rivet Nuts

Threads float inside the nut so you can install a screw at a slight angle to align with off-center parts. They’re also known as Riv-Float nuts.

Rivet Nut Assortments

Heavy Duty Twist-Resistant Rivet Nut Assortments

A ribbed-shaped body holds the nut in place so it won't move when tightening a screw. Assortments contain rivet nuts, mandrels, nosepieces, and a plier-style installation tool.

Rivet Nut Assortments

These rivet nuts have a smooth body and fit in smaller holes than twist-resistant rivet nuts. Assortments include rivet nuts, mandrels, nosepieces, and a plier-style installation tool.

Low-Profile Rivet Nut Assortments

Use these rivet nuts for light duty fastening in low-clearance applications. Assortments include rivet nuts, mandrels, and an installation tool.

Rivet Nut Tools

Wrench-Driven Rivet Nut Tools

Use these tools to install most styles of rivet nuts. Use a wrench to hold the tool and a ratchet to tighten the nut.

Hand-Driven Tools for Low-Profile Rivet Nuts

Turn these tools by hand to install low-profile rivet nuts.

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.

Hydraulic/Air-Powered Rivet Nut Tools

Install all styles of rivet nuts more quickly than cordless rivet nut tools.
