Extended Closed-End Blind Rivet Nuts for Thick Sheet Metal

Extended Blind Rivet Nuts: High-Performance Fastening Solutions for Automotive and Industrial Applications

Extended blind rivet nuts are engineered for demanding applications where standard blind rivet nuts cannot provide sufficient depth or thread engagement. With their closed-end design, high thread strength, and versatile material options, these fasteners are ideal for fastening thick sheet metal, automotive battery packs, machinery enclosures, and heavy-duty industrial assemblies.

Key Features of Extended Blind Rivet Nuts

1. Extended Design for Thick Materials

The longer body of extended blind rivet nuts allows secure riveting in sheet metal up to 13 mm thick, ensuring high thread engagement without damage. This makes them essential for automotive chassis, battery mounts, and industrial panels where deeper material penetration is required.

2. Closed-End Sealing for Environmental Protection

The closed-end design prevents dust, moisture, and contaminants from entering critical assemblies. In new energy vehicle (EV) battery packs, reliable sealing at rivet nut connection points ensures waterproofing, dustproofing, and vibration resistance, safeguarding against short circuits and thermal runaway.

3. Diverse Head Styles for Design Flexibility

Extended blind rivet nuts are available in flat-head, countersunk-head, round-head, half-hex, full-hex, and knurled designs, enabling flush or recessed installation for both aesthetic and functional requirements in automotive interiors, electronic control boxes, and industrial equipment panels.

4. Easy One-Sided Installation

Compatible with standard rivet guns, these fasteners support single-sided riveting, allowing assembly in tight or enclosed spaces such as motor housings, battery pack enclosures, and machinery cabinets. This feature improves production efficiency and simplifies assembly in complex structures.

5. Material and Corrosion Resistance Options

Manufactured from carbon steel, stainless steel, or zinc-plated finishes, extended blind rivet nuts offer excellent corrosion resistance and mechanical strength. These options ensure long-term durability in harsh environments, from automotive chassis exposed to vibration and weather to industrial machinery panels subject to wear and impact.

Applications in the Automotive and EV Industry

• Power Battery Packs: The "heart" of a new energy vehicle requires robust, sealed fasteners to withstand -30℃ to 85℃ temperature ranges and continuous vibration. Properly sealed rivet nuts prevent moisture intrusion, short circuits, and thermal runaway, ensuring overall vehicle safety.

• Motor and Electronic Control Systems: Protects internal components from oil, dust, and contamination, extending the service life of motors and electronic modules.

• Lightweight Vehicle Structures: High-strength rivet nuts reduce overall weight without compromising connection reliability, contributing to improved vehicle range.

Industrial Applications

• Machinery Panels and Equipment Enclosures: Extended blind rivet nuts provide secure attachment points for heavy-duty industrial machinery while maintaining airtight performance.

• Elevator and Rail Transit Panels: Durable fasteners for vibration-intensive environments, ensuring long-term structural integrity.      

• Electronic Control Box Mounting: Closed-end sealing prevents ingress of dust and moisture, protecting sensitive electronics.

Why Choose Extended Blind Rivet Nuts?

Selecting extended blind rivet nuts ensures reliable, one-sided connections in thick sheet metal and critical assemblies. Their closed-end design, versatile material options, and installation flexibility make them indispensable for automotive, industrial, and machinery applications where strength, durability, and environmental protection are crucial.
