Semi‑tubular rivets are the most common type of tubular rivet. They feature a blind hole (hollow portion) of a predetermined depth at the tail end, while the shank near the head remains solid. During installation, the hollow end is rolled outward using a setting press, securely clamping the workpieces together. With only the tail end hollow, semi‑tubular rivets combine the high strength of solid rivets with the easy formability of hollow rivets, requiring lower setting force and leaving a clean, smooth surface after setting. They are widely used in applications where both joint strength and appearance matter.
