Choose Steel Rivet Nuts By Body Type
As a supplier, Rivmate offers a variety of carbon steel rivet nut designs—including Round Body, Knurled Body , Half Hex Body and Hex Body —based on the shape of the mounting hole in your product, anti-rotation requirements, sheet metal thickness, and assembly environment.
Round Body Steel Rivet Nuts
Knurled Body Steel Rivet Nuts
Knurled Body features vertical grooves or knurling on the shaft surface, which helps enhance grip and friction against the walls of sheet metal holes, reducing the risk of the rivet nut rotating when the screw is tightened.
Half Hex Body Steel Rivet Nuts
Half Hex Body features a hexagonal structure near the head, while the remaining portion retains a circular or deformable structure. Suitable for assembly applications with medium to high torque requirements.
Full Hex Body Steel Rivet Nuts
The Full Hex Body has an exterior that consists of a complete hexagonal cylindrical structure. It is suitable for high-torque assembly, large-diameter bolt connections, and heavy-duty industrial structures.
Choose Steel Rivet Nuts By Head Type
Depending on the mounting surface, hole type, torque requirements, and assembly space, Rivmate offers Flat Head, Reduced Head, and Countersunk Head options. If you’re unsure which head type to choose, Rivmate will recommend the most suitable one based on your specific assembly needs.
Flat Head Steel Rivet Nuts
The flat-head design is the most common head type for rivet nuts. The flat-head design increases the contact area between the head and the workpiece surface, thereby improving installation stability, making it suitable for general sheet metal assembly.
Reduced Head Steel Rivet Nuts
The reduced head is relatively smaller in size compared to the flat head and is suitable for applications with stricter requirements regarding head protrusion, installation space, or appearance.
Countersunk Head Steel Rivet Nuts
Countersunk steel rivet nuts are suitable for installations requiring a flatter surface. Reduced head protrusion makes them ideal for aesthetic components. Suitable for panels, covers, and exposed structures.
Choose Steel Rivet Nuts By Bottom Structure
Rivmate offers Steel Rivet Nuts with a variety of bottom configurations, including standard open-bottom and closed-bottom designs, as well as other specialized configurations. You can select the bottom configuration that best suits your assembly needs based on whether the back of the product needs to be sealed, as well as requirements for dust protection, protection against foreign object ingress, and material strength.
Open End Steel Rivet Nuts
Open-End steel rivet nuts are common. The base is open, allowing bolts to pass through the rivet nut, with fewer restrictions on bolt length.Suitable for most general industrial assembly applications.
Closed End Steel Rivet Nuts
Closed-End feature a closed base that prevents bolts from protruding. This effectively reduces the ingress of dust and moisture into the threaded end. They are suitable for enclosed spaces and outdoor structures.

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 steel rivet nuts
Steel rivet nuts are ideal for creating secure internal threaded connections in thin sheets, sheet metal parts, enclosures, equipment housings, and industrial structural components. Select the appropriate model based on the specific assembly location for your application.
Automotive Industry
Automotive body component brackets, interior mounting points, battery enclosures, and chassis components typically feature thin sheet metal with limited space on the back side, making them ideal for assembly using steel rivet nuts, which provide stable threaded connections and facilitate future disassembly and maintenance.
Transportation Equipment
Trucks, trailers, buses, rail vehicles, and body structures are subject to prolonged vibration and require maintenance. Steel rivet nuts provide more stable threaded fastening points than standard nuts.
HVAC Equipment
In HVAC equipment, filter screens, access panels, brackets, and faceplates can only be installed from one side, making it impossible to place nuts on the opposite side. This makes them particularly suitable for single-sided riveting with steel rivet nuts.
Electrical Enclosures
In electrical enclosures, welding is not suitable for securing mounting rails, electrical components, grounding parts, doors, covers, and internal brackets, as it can damage the surface of the workpiece. Steel rivet nuts can be pre-riveted onto the enclosure panels to create threaded points, facilitating subsequent assembly.
Industrial Machinery
Machinery housings, guards, access doors, side panels, and mounting panels often require repeated disassembly. Using steel rivet nuts provides a more stable internal threaded connection and reduces the risk of thread damage in thin sheets.

1.What factors affect the price of steel rivet nuts?
The price of steel rivet nuts is influenced by the material, thread size, riveting range, head type, shank structure, base structure, surface treatment, purchase quantity, inspection requirements, and packaging method.
2.What types of materials can steel rivet nuts be installed into?
Steel rivet nuts can be installed on carbon steel sheets, galvanized sheets, stainless steel sheets, aluminum sheets, thin sheet metal parts, and certain composite or plastic sheets. When used on aluminum sheets or softer metal sheets, pay attention to the sheet thickness, hole diameter, and installation pressure to prevent deformation of the sheet during riveting. When used on plastic sheets, composite materials, or low-strength sheets, we recommend using Jack Nuts or Slotted Rivet Nuts.
3.What are the best methods for rust prevention on installed steel rivet nuts?
You should select the appropriate surface treatment for steel rivet nuts based on the application environment. For general indoor sheet metal, electrical enclosures, and mechanical housings, galvanized or color-coated galvanized finishes are suitable. For outdoor applications, automotive components, transportation equipment, and industrial projects requiring high corrosion resistance, consider zinc-nickel alloy, Dacromet, or Geomet coatings. In humid or coastal environments subject to long-term corrosion, stainless steel rivet nuts are the best choice.
4.What are common sealing solutions used with steel rivet nuts for watertight applications?
Closed-end steel rivet nuts are the most common choice; their closed-end design prevents water, dust, or foreign objects from entering through the bottom of the threads. They also include EPDM gaskets, rubber washers, O-rings, sealing washers, thread sealant, hole-edge sealant, and a protective coating applied after installation.
5.Wholesale prices on steel rivet nuts for contractors.
Rivmate offers wholesale prices on steel rivet nuts for OEM manufacturers, producers, and industrial project buyers. We support bulk purchases of standard specifications, mixed-specification orders, and custom steel rivet nuts.
