Choose round rivet nuts By Bottom Structure
Round rivet nuts can be classified into open-end round rivet nuts and closed-end round rivet nuts based on the design of their bases. The different base structures are suited for different applications; please select the appropriate type based on your product’s requirements.
Open End Round Rivet Nut
Open-End Round Rivet Nuts have an open bottom, making them suitable for assembly with standard bolts. They are highly versatile and easier to install than closed-end designs.
Closed End Round Rivet Nut
Closed-End Round Rivet Nuts have a sealed bottom, which prevents dust and liquids from entering from below. Suitable for assembly locations where the internal space needs to be protected.
Choose round rivet nuts By Head Type
Round rivet nuts supplied by Rivmate are categorized by head type into Flat Head, Reduced Head, Countersunk Head, and other types. The choice of head type affects the surface height of the workpiece, the contact area, the aesthetic appearance, and the load-bearing capacity of the sheet metal.
Flat Head Round Rivet Nut
Flat head round rivet nuts are highly versatile. Flat head is relatively flat but not completely flush. Flat head round rivet nuts provide a stable contact area and are suitable for most sheet metal connections.
Reduced Head Round Rivet Nut
Reduced head rivet nuts have a smaller contact area than flat-head rivet nuts. They protrude less after installation. Suitable for panels with limited installation space and where appearance and minimal protrusion are required.
Countersunk Head Round Rivet Nut
Countersunk head rivet nuts have a countersunk head and require a countersunk hole to be pre-drilled in the workpiece. They are particularly suitable for assembly locations where a flatter surface or a head recessed into the workpiece surface is required.

Steps of Rivet Nuts 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.

Applications of round rivet nuts
Installing round rivet nuts requires standard round holes, which are easy to machine. They have a wide range of applications and are suitable for high-volume industrial assembly.
Sheet Metal Enclosures
This type of material is relatively thin and not suitable for direct tapping or welding. Round Rivet Nuts can be installed in round holes to improve assembly efficiency and connection stability for thin sheets.
Electrical Enclosures
Round Rivet Nuts support single-sided installation, making them suitable for assembly after the cabinet has been formed. This installation method offers greater flexibility than welding rivet nuts. They are commonly used for door panels, brackets, mounting rails, and access panels
Industrial Equipment Enclosures
Round Rivet Nuts reduce surface defects caused by welded nuts and tapping processes. They facilitate future maintenance and disassembly. They are used on equipment doors, covers, nameplates, sensor brackets, or internal structural components.
Tubing and Enclosed Profiles
In tubing, frames, and enclosed profiles, access is limited to one side, making it impossible to install standard rivet nuts from the back. However, Round Rivet Nuts support single-sided installation and provide reusable internal threads.
Home Appliances and Light Industrial Assembly
Home appliance enclosures, small equipment, metal panels, and light industrial products require future maintenance and component replacement. Round Rivet Nuts provide stable threaded connection points to facilitate repairs.

1.How to select round rivet nuts for high-temperature environments？
In high-temperature environments, it is recommended to prioritize stainless steel round rivet nuts, as stainless steel offers better heat resistance, corrosion resistance, and long-term stability compared to standard carbon steel, galvanized, and aluminum rivet nuts, making it more suitable for high-temperature or thermal cycling environments.
2.How to correctly measure for the proper round rivet nut size.
To select the appropriate round rivet nut, you must confirm the thread size, mounting hole diameter, sheet metal thickness, available installation space, and head type requirements. Ensure that the thread size matches the bolt. The hole diameter must match the outer diameter of the rivet nut to ensure that it can be inserted correctly and engage securely. The sheet metal thickness must fall within the product’s grip range to ensure that the sheet metal is securely clamped after riveting.
3.How to achieve a flush finish with round rivet nuts in sheet metal？
To achieve a more flush installation when using round rivet nuts in sheet metal, you should choose countersunk head round rivet nuts. A suitable countersink hole must be pre-drilled in the workpiece surface. The countersunk head allows the rivet nut to be recessed into the sheet metal surface, thereby reducing protrusion and maintaining a flat surface. If the sheet metal is too thin to accommodate countersinking, consider using a reduced-head rivet nut to minimize the exposed head.
4.Preventing material deformation when setting round rivet nuts？
To prevent sheet metal deformation during the installation of Round Rivet Nuts, it is necessary to verify that the sheet thickness, hole diameter, clamping range, head design, installation tool stroke, and sheet strength are properly matched. If the hole diameter in the workpiece is too large or too small, it can cause abnormal stress distribution during installation, leading to loosening or deformation. If the clamping range is not matched to a suitable rivet nut, it may cause bulging or indentations in thin sheets. When applying to aluminum sheets or thin materials, prioritize flat-head rivet nuts with a large support area to avoid deformation caused by excessive stress.
5.Factors influencing round rivet nut pricing for custom orders？
The price of custom Round Rivet Nuts is influenced by thread size, material, body structure, head type, base structure, clamping range, surface treatment, order quantity, inspection requirements, and packaging method.
Galvanized carbon steel Round Rivet Nuts are relatively inexpensive and easy to control in terms of cost. Stainless steel, aluminum, special surface treatments, closed-body structures, small-batch orders, or strict inspection requirements will all gradually increase procurement costs.
