As modern industries push the boundaries of structural lightweighting, securing heavy-duty threads in fragile substrates has become a critical engineering hurdle.
our Four-Prong Slotted Expansion Rivet Nuts offer a premium fastening solution specifically designed for thin sheets, plastics, and composite materials.
This product represents the pinnacle of precision manufacturing, tailored to meet the stringent reliability and stability standards required by European and American Tier 1 suppliers.
Key Features: The Synergy of Cold Forging and CNC Precision
Enhanced Structural Integrity: By utilizing the Cold Forming process, we maintain a continuous grain flow within the metal. This results in superior mechanical properties and fatigue resistance compared to standard machined-only components.
High-Precision Threading: Each rivet nut undergoes secondary CNC machining to ensure strict internal thread tolerances. This precision guarantees seamless bolt engagement on automated assembly lines, significantly reducing the risk of cross-threading and production downtime.
Technical Highlights: Optimized Expansion for Advanced Composites The core innovation lies in the precision-engineered "Four-Prong Slotted" shank. During the setting process, the shank splits into four wide, symmetrical legs, creating a "tulip-shaped" expansion on the blind side:
Exceptional Surface Area Support: The expanded footprint provides several times the bearing area of a standard rivet nut, delivering industry-leading Pull-out Strength even in ultra-thin materials.
Base Material Protection: The uniform distribution of clamping force prevents cracking, delamination, or deformation in sensitive substrates such as carbon fiber (CFRP), reinforced plastics, or soft alloys.
Superior Anti-Rotation (Torque-to-turn): The four-prong structure creates a robust mechanical interlock on the blind side, ensuring high vibration resistance and exceptional torque-to-turn performance.
Application Scenarios
Automotive Industry: Lightweight composite body panels, door modules, instrument panel carriers, and EV battery enclosure components.
Aerospace & Marine: Carbon fiber interior fittings, maritime composite decking, and vibration-prone instrumentation panels.
Industrial Equipment: Thin-walled tubing, outdoor telecommunication cabinets, and maintenance panels requiring high-cycle disassembly.
