Classified by Bottom Structure
Rivmate offers two types of rivet nuts: open-end flat-head rivet nuts and closed-end flat-head rivet nuts. When making your selection, you should consider whether you need the closed-end type.
Open End Flat Head Rivet Nuts
It features a through-hole threaded design. Once installed, the bolt passes through the rivet nut, making it suitable for most standard sheet metal fastening applications.
Closed End Flat Head Rivet Nuts
Classified by External Surface Structure
Rivmate flat-head rivet nuts can be classified based on their external surface profiles, which primarily include full hex, half hex, cylindrical, and knurled cylindrical designs. Different external surface profiles directly affect anti-rotation performance, assembly stability, and application costs.
Full Hex Flat Head Rivet Nuts
It features a full hexagonal shank design. Installation requires alignment with hexagonal mounting holes, providing highest resistance to rotation. It is suitable for assembly locations requiring high anti-rotation performance.
Half Hex Flat Head Rivet Nuts
It features a partial hexagonal shank design. It offers anti-rotation performance and installation flexibility. Compared to standard round-shank rivet nuts, the semi-hexagonal design provides better resistance to rotation.
Round Body Flat Head Rivet Nuts
It features a cylindrical external structure. It can be installed in standard round holes, offering high installation compatibility. It is cost-effective and suitable for general sheet metal fastening applications.
Knurled Body Flat Head Rivet Nuts
Its outer surface features a knurled or serrated pattern. This enhances the grip between the rivet nut and the hole wall, thereby reducing the risk of rotation and improving assembly stability.

Steps of Rivet Nut Installation
- Insert the rivet nut into the pre-drilled hole, ensuring that the head of the rivet nut is flush with the surface of the workpiece.
- Screw the pull rod of the rivet nut gun into the internal threads of the rivet nut, and hold the tool vertically.
- Activate the rivet nut gun and pull the rod to expand and deform the tail end of the rivet nut, clamping it securely to the workpiece.
- Once riveting is complete, retract the rod in the opposite direction. Check that the rivet nut is secure and confirm that the head is flush with the surface.
Flat Head Rivet Nuts Quality Inspection
Rivmate is equipped with a dedicated flat-head rivet nut testing laboratory. This facility is used to verify the thread accuracy, dimensional stability, sheet metal thickness compatibility, anti-rotation capability, pull-out resistance, and batch consistency of blind rivet nuts.
- Complete Set of Rivet Nut Testing Equipment
- Consistent Batch Quality
- 99.9% pass rate
Using universal testing machines, salt spray test equipment, dimensional inspection tools, and riveting simulation equipment, we can test key performance metrics during sample validation, mass production, and prior to shipment. This helps customers reduce the risk of failure and rework costs during mass assembly, ensuring a more consistent supply of flat-head rivet nuts.
Flat Head Rivet Nuts Surface Finish Options
Different application environments have different surface treatment requirements. Surface treatment directly affects a product’s corrosion resistance, visual consistency, and service life. Rivmate can customize surface treatments based on the customer’s specific application environment requirements.
- Provides basic corrosion protection
- Maintains a consistent appearance
- Extends the product's service life
Rivmate’s customizable surface treatments for rivet nuts include zinc plating, nickel plating, passivation, blackening, zinc-nickel plating, and custom colors. If your project has specific requirements regarding color, corrosion resistance, appearance, or testing, please send samples, drawings, and details of the operating environment to Rivmate. We will evaluate the most suitable surface treatment solution based on your actual needs.
Applications of flat head rivet nuts
Flat-head rivet nuts sit flush against the workpiece surface, providing a larger load-bearing area. They are suitable for sheet metal assemblies that require better support at fastening points, easier installation, and more secure clamping performance.
Thin Sheet Metal Panels Without Countersinking
Due to the limited thickness of thin sheet metal panels, countersinking can easily cause the sheet to deform. Flat-head rivet nuts provide a larger bearing surface and are therefore better suited for joining thin sheets.
Painted or Powder-Coated Sheet Metal Assemblies
Sheet metal parts that have already been powder-coated, painted, or otherwise surface-treated. Flat-head rivet nuts can be installed in pre-drilled holes without damaging the coating. They also reduce the need for rework after painting.
Access Panels and Maintenance Covers Requiring Repeated Screw Removal
Inspection covers and maintenance panels need to be removed frequently for maintenance. Flat-head rivet nuts allow screws to be repeatedly tightened and removed, and can be paired with knurled or hexagonal designs to enhance anti-rotation performance.

How to choose flat head rivet nuts for aluminum panels
First, you need to confirm the total thickness of the aluminum sheet, the mounting hole diameter, the thread size, and the torque requirements. This will help prevent unstable riveting.
Next, select the material. Since aluminum sheets are generally lightweight, choose aluminum flat-head rivet nuts. If rotational resistance is a concern, you can opt for a hexagonal design.
Finally, determine whether corrosion protection is needed and select the appropriate surface treatment.
Difference between flat head and low profile rivet nuts.
Flat-head rivet nuts have a larger head contact area. They provide greater support at the edge of the hole. They are better suited for thin sheet metal and aluminum sheets.
Low-profile rivet nuts have a lower, smaller head. They place higher demands on the installation hole diameter, sheet thickness, and sheet strength. They are suitable for locations with limited space or where appearance is a key consideration.
What is the maximum grip range for flat head rivet nuts?
The maximum grip range for flat head rivet nuts is 8.9mm
What are the advantages of using flat head rivet nuts?
