Which is the most common type of connector for structural steel?

• A. Rivets
• B. Adhesives
• C. Bolts
• D. Welds

Answer: (C)

In structural steel work, the most practical way to join members is with bolts. Bolted connections are fast to erect in the field, you can adjust and retighten them as needed, and they transfer loads reliably through high‑strength bolts without the heat input and distortion that welding can cause. This makes bolted joints easier to inspect, maintain, and retrofit if a replacement is needed, and they tend to be more economical on many projects because you can assemble large sections quickly with less specialized skill than required for welding. Rivets have largely fallen out of new construction because they require intensive labor and precision riveting on site, which is slower and less versatile. Adhesives don’t provide the strength, ductility, and fatigue resistance needed for primary structural connections in steel frames. Welds are important and widely used, but they demand skilled labor, careful control of heat and distortion, and more on-site time, making bolts the more common solution overall.
