About Nuts, Materials, and Finishes

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.

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.

Twist-Resistant Rivet Nuts for Soft Materials

Wedges under the flange lock the nut in place in soft materials such as brass and aluminum.

Heavy Duty Twist-Resistant Rivet Nuts

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

Screw-to-Install Rivet Nuts

These rivet nuts are mildly corrosion resistant.

Scratch-Resistant Screw-to-Install Rivet Nuts

A PVC coating minimizes the chance of scratching the surface of your material. These rivet nuts are more corrosion resistant than zinc-plated steel rivet nuts.

Sealing Screw-to-Install Rivet Nuts

The coated flange seals out moisture and prevents corrosion.

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.

Steel Rivet Nuts

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

Aluminum Rivet Nuts

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

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.

Steel Low-Profile Rivet Nuts with Installation Tool

These kits include one size of low-profile rivet nuts.

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.

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.

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.

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.

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 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.

Rivet Studs

Add a stud to thin material when you only have access to one side.
