About Thumb Screw and Binding Post Materials

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.

Twist-Resistant Rivet Nuts for Soft Materials

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

Sealing Screw-to-Install Rivet Nuts

The coated flange seals out moisture and prevents corrosion.

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.

Screw-to-Install Rivet Nuts

These rivet nuts are mildly corrosion resistant.

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.

Aluminum Rivet Nuts

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

Steel Rivet Nuts

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

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.

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.

Binding Barrels and Screws

18-8 Stainless Steel Binding Barrels and Screws

These include a barrel and a screw.

18-8 Stainless Steel Binding Barrels

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 18-8 stainless steel, they are chemical resistant.

18-8 Stainless Steel Screws for Binding Barrels

Pair these screws with a barrel you already have or couple with a different barrel to create a custom fastener. Made from 18-8 stainless steel, they are chemical resistant.

Super-Corrosion-Resistant 316
Stainless Steel Binding Barrels

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Super-Corrosion-Resistant 316 Stainless
Steel Binding Barrels and Screws

These include a barrel and a screw with an extra-wide (truss) head. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Super-Corrosion-Resistant 316 Stainless
Steel Screws for Binding Barrels

Pair with a barrel you already have or couple with a different barrel to create a custom fastener. Made from 316 stainless steel, they have excellent chemical resistance and can be used in saltwater environments.

Steel Binding Barrels and Screws

These include a barrel and a screw.

Steel Binding Barrels

Use these barrels with a screw you already have or pair with a different type of screw to create a custom fastener. They're zinc plated to resist corrosion in wet environments.

Steel Shoulder Screws for Binding Barrels

Designed with a shoulder for the strength to handle side and shear loads.

Steel Screws for Binding Barrels

Shorter than shoulder screws for use in thin material.

Hex Drive Binding Barrels and Screws

Use these hex drive screws and binding barrels as a low-profile alternative to standard nut and bolt combinations.

Recessed Joint Clamps for Wood

Install in a cutout to create a secure joint between boards, butcher blocks, and countertops.

Binding Barrels and Screws for Wood

Create strong joints in wood and wood composite.

Dowel Nuts for Wood

Create a strong joint in a blind hole.

Flat Head Binding Barrels and Screws

Angled under the head for a flush finish in countersunk holes.

Tamper-Resistant Torx Binding Barrels and Screws

A tamper-resistant Torx driver is required for installation and removal.

18-8 Stainless Steel Binding Barrels
and Screws for Door Hardware

These binding barrels and screws have good chemical resistance.

Super-Corrosion-Resistant 316 Stainless Steel
Binding Barrels and Screws for Door Hardware

More corrosion resistant than 18-8 stainless steel binding barrels and screws, these have excellent resistance to chemicals and salt water.

Brass Binding Barrels and Screws for Door Hardware

Brass binding barrels and screws are corrosion resistant in wet environments and electrically conductive.

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.

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 Studs

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

Tools for Blind Rivets and Rivet Nuts

Generate enough force with the assistance of a self-contained hydraulic system to install blind rivets with one hand.

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.

Lever-Style Rivet Nut Tools

Use two hands to maximize leverage when installing smooth body rivet nuts.

Lever-Style Rivet Nut Tools with Visual Stroke Indicator

Use these tools to install smooth and ribbed body rivet nuts. An indicator allows you to ensure your rivet nut installs correctly.

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.

Plier-Style Rivet Nut Tools

Install smooth body rivet nuts.

Light Duty Plier-Style Rivet Nut Tools

Install screw-to-install rivet nuts and rivet nuts for plastic and composites.
