Semi-hollow rivets (also known as semi-tubular rivets) are lightweight fasteners with a solid head and hollow tail, balancing the strength of solid rivets and the easy installation of hollow rivets. Manufactured by cold heading, they are available in stainless steel, carbon steel, aluminum and copper, with sizes M1.2–M10 compliant with GB/T 873/874/875 standards. The hollow tail deforms easily during riveting for tight filling, ensuring secure fastening with low installation force. Ideal for thin sheets and soft materials in luggage, electronics, furniture and automotive interiors, they support custom head types, dimensions and finishes (zinc plating, anodizing) for diverse applications.
