Solving Limited Access Assembly Challenges
In complex manufacturing environments like enclosure fabrication or automotive bodywork, accessing both sides of a joint is often impossible. Our “Rivets and Rivet Nuts” category addresses this specific engineering constraint. As dedicated industrial fasteners manufacturers, we engineer these components for “blind” installation, meaning they are inserted and set from only one side of the workpiece. This capability is essential for assembling hollow tubing, large ventilation ducts, and closed-frame chassis. Unlike welding, which requires skilled labor and can distort thin metals with heat, our blind rivet series (often referred to as the pop rivet) offers a cold-joining process that is fast, consistent, and requires minimal operator training. This makes them the fastener of choice for high-volume assembly lines seeking to reduce cycle times while maintaining structural rigidity.
Technical Specifications and Head Configurations
Our inventory covers a broad spectrum of head styles and material combinations designed to match specific substrate requirements. We supply the standard Dome Head blind rivet for general-purpose fastening where a low-profile finish is desired. For softer or brittle materials like plastic, fiberglass, or thin aluminum skins, we offer Large Flange heads. The larger surface area of the flange distributes the clamping load, preventing the rivet from pulling through the material during setting. Our material options include Aluminum bodies with Steel mandrels for lightweight strength, as well as All-Steel and Stainless Steel variants for enhanced corrosion resistance. Furthermore, this category includes the rivet nut, a dual-function fastener that not only joins sheets but also provides a permanent internal thread, solving the problem of tapping into materials too thin to support a standard screw thread.
Supply Chain Reliability for Fabricators
Stability in component supply is critical for keeping production lines moving. As a global industrial fasteners supplier, Screwtool manages a robust inventory of standard DIN and ISO specifications to support urgent fabrication needs. We understand that aesthetic integration is often as important as mechanical holding power; therefore, we offer specialized options such as painted rivets. Whether you require a black, white, or custom-colored head to match a pre-coated appliance casing or architectural panel, we can supply it directly. By integrating the rivet nut and rivet supply chain, manufacturers can source all their sheet metal joining solutions from a single point. Our strict quality control ensures that mandrels break at the correct tension point every time, preventing loose joints or tool jamming that can occur with inferior consumables.
Advantages
Load Distribution and Material Compatibility
A key technical advantage of our Large Flange blind rivet is its ability to protect the structural integrity of delicate mating materials. In applications involving soft aluminum siding or polycarbonate sheets, a standard fastener might crack the substrate under load. Our large flange design increases the bearing area, effectively reducing the pressure per square millimeter. Additionally, by offering various metallic combinations (such as Al/St or St/St), we allow engineers to manage galvanic corrosion risks. For instance, using an aluminum pop rivet on an aluminum panel prevents the galvanic reaction that would occur with a steel rivet, ensuring the assembly’s longevity in outdoor environments.
Dual-Functionality of Threaded Inserts
The rivet nut represents a significant leap in assembly efficiency for thin-walled applications. Traditionally, attaching a component to a 1mm thick sheet required welding a nut or using a loose backing washer—both of which are labor-intensive. Our rivet nuts provide a “install-and-forget” solution. Once set, the knurled or hexagonal body of the insert bites into the parent material, providing high torque-to-turn resistance. This creates a reusable, load-bearing thread that rivals a standard nut, allowing for the easy attachment of removable service panels, electrical components, or brackets. For industrial fasteners manufacturers, this innovation eliminates the need for backside access during final assembly, simplifying the design of complex machinery.
Aesthetic Integration and Finish Quality
In consumer-facing products like white goods or architectural facades, the visual appearance of fasteners is paramount. We distinguish ourselves from a generic industrial fasteners supplier by offering factory-applied painted finishes on our rivets. Instead of requiring manufacturers to paint over the fastener head after assembly—which often leads to chipping or poor adhesion—our pre-painted blind rivet heads are cured for durability. This ensures that the color remains consistent and the finish withstands the setting force of the rivet gun. This attention to detail allows for a seamless visual blend with the product surface, enhancing the perceived quality of the final item without adding a secondary finishing step to the production workflow.
Use Scenarios
HVAC Ducting and Ventilation Systems
A Commercial HVAC Contractor fabricating large-scale air handling units relies on rapid joining methods for galvanized steel sheets. Welding is not feasible due to the zinc coating, which produces hazardous fumes and ruins the corrosion protection. The contractor selects Screwtool’s Steel/Steel Dome Head blind rivet to join the duct seams. The high shear strength of the steel mandrel ensures the ducts can withstand high static air pressure without bursting. As a reliable industrial fasteners supplier, we provide these rivets in bulk to the job site, ensuring the installation crew can rapidly seal hundreds of feet of ductwork using pneumatic tools, maintaining air-tight integrity throughout the building’s ventilation network.
Specialty Vehicle Conversion
An Automotive Upfitter converting cargo vans into mobile workshops needs to attach heavy shelving units and tool racks to the vehicle’s interior walls. The van’s structural ribs are made of thin box sections where there is no access to the inside to hold a nut. The upfitter uses Screwtool’s M6 and M8 rivet nut inserts. By drilling a hole and setting the rivet nut from the outside, they create a robust anchor point. This allows the shelving to be bolted securely and removed later if the vehicle configuration changes. The knurled body of the rivet nut prevents it from spinning when the bolts are tightened, ensuring a secure installation that withstands the vibration of the moving vehicle.
Signage and Architectural Cladding
A Signage Manufacturer builds large outdoor aluminum displays that must withstand wind loads and weather exposure. To attach the aluminum composite face panels to the internal frame, the manufacturer uses our Large Flange pop rivet. The wide head prevents the composite material from cracking around the hole during wind gusts. Furthermore, to maintain the clean look of the white signage background, they specify our White Painted Head rivets. Sourcing from experienced industrial fasteners manufacturers allows them to get the exact color match and grip range needed, ensuring the fasteners are barely visible to the public while providing a permanent, weather-resistant bond.

FAQ
What is the difference between a blind rivet and a rivet nut?
A blind rivet (or pop rivet) is used to permanently join two pieces of material together. A rivet nut, however, anchors into a single sheet to provide a reusable internal thread for a bolt or screw.
Do you offer rivets with colored heads?
Yes, as a flexible industrial fasteners supplier, we can provide blind rivets with heads painted to specific RAL colors (e.g., Black, White) to match your product’s casing or siding seamlessly.
What materials are your blind rivets available in?
We manufacture rivets in various combinations to suit different strength and environment needs, including Aluminum body/Steel mandrel, All-Steel, All-Stainless Steel, and Aluminum/Stainless Steel.
Can I get free samples for testing?
Yes, if we have the specific pop rivet or insert in stock, we provide free samples for quality verification, with the customer only covering the freight cost. Custom samples may incur a setup fee.
What creates the thread in a rivet nut?
The rivet nut comes pre-threaded. When installed, the unthreaded portion of the body collapses to clamp onto the sheet metal, leaving the internal thread intact and ready to accept a bolt.
