Round Rivet Nuts

Round Body Style

Round bodied rivet nuts, designed for round holes, feature either a smooth or knurled external shank surface. While both features provide minimal spinout resistance, knurled shanks offer additional torque resistance by "biting" into the desired work piece. Round rivet nuts are also manufactured with closed ends. These closed ends provide a barrier that prevents the exchange of gases or liquids across the installation side and blind side of the parent component.

  • Provides strong threads in material too thin to tap
  • Simple, blind installation
  • Suitable for automated production lines

Hexagonal Rivet Nuts

Hexagonal Body Style

Hexagonal rivet nuts provide excellent spinout resistance and are recommended when hexagonal holes are available. Full hexagonal, or full hex, rivet nuts possess a hex shaped shank and are designed for heavy duty applications. Hydro‑pneumatic spin‑pull tools are the recommended method for installing full hex rivet nuts. Half hexagonal, or semi hex, rivet nuts feature a hex shank under the head flange that tapers into a round shank. These are often used for lighter duty applications and can be installed using most types of rivet nut tools.

  • Exceptional spin‑out resistance over round body rivet nuts
  • Offered in large or small flange varieties for proper application fitment
  • Available in a variety of corrosion resistant finishes

Slotted Rivet Nuts

Slotted Body Style

Slotted rivet nuts, sometimes called plus nuts or cross nuts, feature a round slotted body with a straight shank or pre‑bulbed shank for increased spin-out resistance. This slotted series of rivet nut offers a large grip range that is ideal for single, variable, or multiple thickness materials. The large backside foot print provided by slotted rivet nuts allows for increased pullout resistance in plastics, composites, and thin sheet metal applications.

  • Fully plated with corrosion resistant finishes
  • Designed to be installed in plastics without surface distortion
  • Easily installed using manual hand rivet nut tools

Swaged Rivet Nuts

Swaged Body Style

Swaged rivet nuts provide strong threads in thicker sheet materials, tubing or blind holes requiring reduced clearance. The unique design allows a portion of the rivet nut to pull up into the shank during installation. This forces the walls of the rivet nut outward into the attached component, wedging the fastener firmly into the work piece.

  • Unique design provides a shorter installed profile of the fastener
  • Closed end shanks available for liquid and gas applications
  • Increased wall thickness provides improved shear strength

Floating Rivet Nuts

RIV-FLOAT Body Style

Floating rivet nuts are designed with threads that “float” inside the rivet nut body. This feature allows machine screws to be installed at an angle, thus providing efficient, accurate assembly of components, nearly eliminating risk of cross threading and spin out. Floating rivet nuts also compensate for misalignment caused by tolerance stack up or during servicing of a joint. These fasteners are available in short and long shanks to accommodate different substrate thicknesses and clearance requirements.

  • Accurate attachment of off center applications
  • Use of a hydro‑pneumatic spin‑pull rivet nut tool is recommended for installation
  • Ideal replacement for riveted nut plates or cage nuts

Rivet Nut Studs

Stud Body Style

Rivet nut studs are a two‑piece fastener composed of a rivet nut body and a male threaded stud. Once installed, the threaded stud extends beyond the work piece, allowing for threaded conventional fasteners to be used. These are ideal for attaching thin material in blind applications and a great alternative to clinch or weld studs.

  • Lower total installed cost compared to weld on studs
  • Can be installed in pre‑painted components
  • Allows for easier component placement until final assembly with a mating nut

What is a rivet nut?

A rivet nut, also known as a blind threaded insert, is a one‑piece internally threaded fastener with an engineered body that compresses when installed, thus securing the fastener in place. They are commonly installed in applications with blind fastening requirements, however, they have become more frequently utilized in high production volume environments due to simple installation and economical costs. Rivet nuts can be installed on pre‑painted components without distorting the base material and are a suitable replacement for weld nuts, eliminating weld spatter and toxic fumes.

What is a blind insert?

A blind insert, or blind threaded insert, is another term for the more commonly known rivet nut. For more details on blind inserts, check out our rivet nut features section!

How do rivet nuts work?

Rivet nuts, also called blind thread inserts, are used to provide a strong threaded anchor point in thin or brittle substrates that are not suited for tapping. When installed, the body of the nut collapses, creating a bulge that pinches the substrate between it and the nut flange.

What kind of rivet nut do I need?

Some considerations should be taken into account when choosing the right rivet nut for your application. While body style is often the most important, there are other attributes that should be factored in the decision making process. Take a look at our guide to assist you in making the right choice for your needs!

Rivet Nut Body Style Features:

There are numerous variations of rivet nut bodies to choose from. We've compiled a list of the most popular styles offered by G.L. Huyett!

  • Round Rivet Nuts: Round bodied rivet nuts feature either a smooth or knurled surface. While both provide minimal spinout resistance, a knurled surface provides additional torque resistance.
  • Hexagonal Rivet Nuts: Hexagonal rivet nuts provide the ultimate spinout resistance. Full hexagonal, or full hex, rivet nuts are designed for heavy duty applications. For lighter duty needs, half hexagonal rivet nuts are suitable. Hexagonal nuts are recommended if hex shaped holes can be produced.
  • Slotted Rivet Nuts: Slotted rivet nuts feature a round slotted body and are available with a straight or pre‑bulbed shank. Both varieties offer a large grip range for variable material thicknesses, as well as a large footprint for increased pullout resistance. Pre‑bulbed shanks provide some spinout resistance.
  • Swaged Rivet Nuts: Swaged rivet nuts provide strong threads in thicker sheet materials, tubing, or blind holes requiring reduced clearance. The unique swaging design allows the threaded portion of the rivet nut to separate and pull up into the shank, creating a bulge that wedges the rivet nut firmly into the work piece.
  • Floating Rivet Nuts: Floating rivet nuts can compensate for misalignment caused by tolerance stack up or servicing of joint. Body lengths are often designated as standard or short to accommodate different substrate thicknesses.
  • Rivet Nut Studs: Rivet nut studs, or studded rivet nuts, are a two‑piece fastener composed of a rivet nut body and a male threaded stud. These are suitable for attaching thin material in blind applications and a great alternative to clinch or weld studs.

How to install rivet nuts:

Rivet nuts, or blind threaded inserts, can be installed using simple or specialized rivet nut tools. The most common rivet nut tools are manual hand tools, pneumatic spinߛspin rivet guns, and hydroߛpneumatic spinߛpull rivet guns.

  • Manual Hand Installation — Hand installation of rivet nuts can be accomplished using a variety of manually powered hand tools. The most common types are ratchet, lever, and hand. To use, simply thread the insert onto the end of the tool and action the tool until the side wall of the rivet nut has collapsed, securely pinching the parent material. Manual hand installation is great for small production quantities and prototyping.
  • Pneumatic Tools — Pneumatic, or spin‑spin, rivet nut tools are air powered pneumatic tools that feature either a pistol grip, right angle, and inline form factor. The rivet nut is threaded onto the mandrel which is spun inward, collapsing the walls of the rivet nut. Once the walls are fully collapsed, the tool reverses and separates from the installed fastener.
  • Hydro‑pneumatic Tools — Hydro‑pneumatic, or spin‑pull, rivet nut tools use a combination of compressed air and hydraulics to install rivet nuts. To install a rivet nut using a spin‑pull rivet nut tool, simply thread the nut onto the end of the tool's mandrel. After the fastener is inserted into the work piece, the mandrel retracts, pulling the threads of the rivet nut into the work piece. Once the rivet nut is installed, the tool unthreads from the fastener.

How does a rivet nut gun work?

Rivet nut guns have three distinct methods for installing blind thread inserts. Spin‑spin, spin‑pull to pressure, and spin‑pull to stroke.

  • Spin‑spin rivet nut guns use air pressure to spin the chuck, or mandrel, of the gun. As the mandrel spins, it draws the body of the insert in. This action collapses the wall of the rivet nut, securing it to the desired substrate. Once the threaded insert is installed, the mandrel reverses its rotation to separate from the fastener. This style of rivet nut gun requires awareness from the operator as to not over‑tighten the rivet nut.
  • Spin‑pull to pressure rivet nut guns install the fastener based on a pre‑set pressure determined by the operator. The rivet nut is threaded onto the mandrel, which retracts, pulling the threads of the fastener into the parent material until a pre‑determined pressure is achieved. Pull to pressure installation is ideal for parts with variable material thickness.
  • Spin‑pull to stroke rivet nut guns install the fastener based on a pre‑set stroke length determined by the operator. The rivet nut is threaded onto the mandrel, which retracts, pulling the threads of the fastener into the parent material until a pre‑determined stroke is reached. Pull to stroke installation is ideal for parts with a uniform material thickness.
