Round Head Stepped Rivets
Round head stepped rivets (also commonly called round head shouldered rivets) are a specialized type of fastener that combines the familiar dome-shaped head with a unique shank design featuring a step or shoulder. This design provides distinct benefits over standard rivets.
- Material: Carbon steel, Stainless steel
- Surface treatment: Nickel-plating
- Dimensions: Custom-manufactured to specific requirements
Superior Features of Round Head Stepped Rivets
- Precise Location and Alignment: The shoulder acts as a built-in pilot, perfectly fitting into a pre-drilled hole in the top material layer. This self-locating feature ensures fast and precise alignment of components, which is critical in high-volume automated assembly.
- Excellent Resistance to Vibration and Loosening: The shoulder fits snugly into the host material, eliminating play or movement. This provides superior anti-vibration properties, making these rivets far more reliable in high-stress or oscillating environments than standard fasteners.
- Even Clamping Force and Reduced Stress: The shoulder bears against the surface of the top material layer, allowing the riveting force to be applied efficiently to clinch the bottom material. This creates a strong, stable joint and prevents distortion or damage to delicate or soft materials.

Applications of Round Head Stepped Rivets
1. Electronics and Electrical Equipment
- Hard Disk Drives (HDDs): Critical due to their high precision and vibration dampening for protecting sensitive internal components.
- Computer Chassis: Used to secure brackets, drive bays, and panels where alignment and grounding are important.
2. Automotive Industry
- Interior Trims: Attaching dashboard components and door panels where vibration resistance to prevent rattles is essential.
- Electrical Systems: Securing wiring harness clips, sensor mountings, and ECU enclosures.
