Engineered for Superior Sealing: High-Performance Waterproof Rivet Nuts
In outdoor equipment, automotive systems, and renewable energy storage, fluid leakage and moisture ingress at sheet metal jointing points are leading causes of corrosion and critical component failure. Designed to overcome these engineering challenges, our Waterproof Rivet Nuts (Closed-End Rivet Nuts) combine robust blind threaded insertion with exceptional sealing integrity, delivering reliable protection in the most demanding environments.
Key Features & Core Advantages
Closed-End Sealed Structure: Features a fully enclosed barrel end that forms a impenetrable physical barrier against water, dust, oil, and gas ingress, preventing internal thread corrosion.
Integrated Sealing Element: Option for pre-installed O-rings (NBR, EPDM, or Silicone) or under-head sealant compounds. Upon installation, the seal compresses against the parent material to achieve IP67/IP68 level protection.
High Anti-Rotation & Pull-Out Resistance: Engineered with knurled or full-hexagonal body styles to maximize grip within the parent sheet, ensuring supreme anti-torque performance under heavy vibration.
Efficient Single-Sided Installation: Allows rapid, cost-effective assembly from one side of the workpiece, making it ideal for closed profiles, tubing, and large enclosures.
Technical Specifications
Materials: Stainless Steel (304 / 316), Carbon Steel (Zinc-Nickel plated, enduring 1,000+ hours salt spray test), and Aluminum Alloy.
Thread Sizes: Metric (M3 to M12) and Imperial (#6 to 1/2"), with custom thread pitches available upon request.
Grip Range: Suitable for sheet metal, composites, and thin-walled tubing thicknesses from 0.5mm to 6.0mm.
Ingress Protection: Designed to meet up to IP68 rating standards (depending on sealing configuration and application setup).
Target Applications
Renewable Energy: Solar inverter enclosures, tracking system supports, and energy storage systems (ESS).
Automotive & Transportation: EV battery pack housing, roof racks, chassis assemblies, and commercial vehicle bodywork.
Industrial Controls & Telecom: Outdoor 5G telecom cabinets, waterproof junction boxes, and smart meter housings.
Marine & Outdoor Hardware: Marine electronics, exterior architectural lighting, and ruggedized outdoor enclosures.
