Rivet nuts, also known as blind threaded inserts, are internally threaded fasteners installed from one side of the workpiece. During installation, the body deforms behind the panel to create a permanent mechanical anchor. The result is a reusable machine thread in thin materials where tapping is not practical.

- Description
- Specifications
Rivet nuts are categorized within the rivet family due to their deformation-based installation method, though functionally they provide a threaded connection for repeated assembly and disassembly.
G-Fast supplies rivet nuts through qualified domestic and global sources and supports specification verification and production blanket programs for industrial customers.
Grip Range and Hole Preparation
Grip range defines the minimum and maximum material thickness over which a rivet nut will form a complete blind-side bulge. Installation outside the specified grip range results in incomplete formation and reduced pull-out or torque-out performance.
Before ordering, confirm:
- Hole diameter and tolerance
- Material thickness at each installation location
- Specified grip range of the selected rivet nut
Open-End vs. Closed-End
| Configuration | Typical Use |
| Open-End | General industrial use; no sealing requirement |
| Closed-End (Sealed) | Moisture, debris, or pressure isolation required |
Closed-end rivet nuts are typically specified where fluid or air passage through the panel wall must be prevented.
Common Applications
- Sheet metal enclosures and panels
- Tubular frames and hollow sections
- Equipment housings and cabinets
- Assemblies requiring repeated bolt removal and reinstallation
Supply & Fulfillment
- Carton quantities available
- Production blanket orders and scheduled releases
- Specification review prior to order placement

Thread Systems and Size Range
Rivet nuts are available in unified inch and metric thread systems. Representative ranges include:
- Unified Inch (UNC / UNF): #6 through 1/2"
- Metric (Coarse and Fine): M3 through M12
Thread size selection determines body diameter, grip range, and installation requirements. Confirm thread engagement depth against load requirements in thin-gauge applications.
Body Styles
| Body Style | Application Consideration |
| Round / Smooth Body | Standard sheet metal with consistent hole preparation |
| Knurled Body | Improved resistance to spin-out in softer materials |
| Hex Body | High-torque applications requiring anti-rotation |
| Large Flange Head | Thin sheet or soft substrates requiring load distribution |
| Countersunk Head | Flush surface requirement on access side |
| Reduced / Low Profile Head | Space-constrained panel applications |
Material Options
- Steel (zinc-plated) – general indoor industrial applications
- Stainless Steel (300 series) – outdoor, washdown, corrosive environments
- Aluminum – lightweight assemblies and aluminum structures
- Brass – electrical or specialty applications
Material selection should consider corrosion exposure and compatibility with the base material to minimize galvanic interaction.
