Wedge Head Rivet Nut Series

【Product Overview】

In modern industrial assembly, the failure of thin-sheet joints is often traced back to rotational loosening caused by vibration. Our Under-head Serrated Rivet Nuts combine Taiwan’s premier Cold Forging expertise with CNC precision to tackle the most rigorous mechanical stresses. By leveraging the work-hardening effects of the cold-heading process, we ensure that each fastener provides maximum structural integrity and thread durability for global Tier 1 suppliers.

【Key Technical Features】

• Aggressive Under-head Serrations: Maximum Torque-to-turn Resistance

  The specialized serrations under the flange bite deeply into the parent material during the setting process. This mechanical interlock provides superior resistance to rotation—surpassing standard rivet nuts by over 30%—preventing spin-out even during high-torque power tool installation.

• Cold Forging Excellence: Continuous Grain Flow

  Unlike machined alternatives, our cold-forged nuts maintain a continuous grain flow, significantly enhancing pull-out strength and fatigue life. This ensures the threads remain intact under dynamic loads.

• CNC-Controlled Tolerances: Ready for Automation

  We guarantee strict dimensional consistency, which is critical for high-speed Auto-feeding systems. The optimized lead-in chamfer ensures seamless insertion, reducing assembly cycle times and operational downtime.

【Application Scenarios】

• Automotive: Chassis reinforcements, EV battery housings, and structural components subjected to constant road vibration.

• Aerospace Interiors: Cabin partition mounting and seating structures where lightweighting must meet absolute safety standards.

• Marine & Energy: Engine room control panels and offshore wind turbine housings requiring extreme salt-spray resistance and vibration dampening.
