A round head rivet is a type of solid rivet characterized by its large, semi-circular (rounded) head that provides a broad bearing surface. This design makes round head rivets strong and reliable fasteners, commonly used in construction, shipbuilding, heavy machinery, and structural applications where durability and load distribution are critical.
Key features of round head rivets :
-
Head shape : Large, smooth, semi-spherical head that sits above the surface of the material.
-
Strength : Provides exceptional strength and resistance to mechanical stresses, making them suitable for heavy-duty applications such as bridges, cranes, aircraft, and marine structures.
-
Material options : Available in various materials including aluminum (lightweight and corrosion-resistant), steel (high strength), brass (strength and corrosion resistance), and stainless steel (excellent for harsh environments).
-
Installation : Installed by inserting the rivet through a pre-drilled hole and then deforming the tail end (called bucking or upsetting) to form a second head, securing the materials together permanently.
-
Advantages : They resist vibration and loosening over time, provide a smooth and aesthetic surface with minimal snagging, and accommodate a wide range of material thicknesses due to their large grip range.
Round head rivets are preferred where strong, permanent joints are needed and are often chosen for their combination of mechanical performance and clean appearance.
