Semi-hollow rivets are rivets whose rivet column is semi-hollow. From this perspective, there are two other types of rivets, solid rivets and hollow rivets. The upper and middle parts of the semi-hollow rivet cylinder are of solid structure, and the tail is of hollow structure. During installation, the hollow part of the tail is squeezed and turned outwards to form a buckle to fix the connecting piece. This type of rivet is one of many non-standard rivets. Many non-standard rivets need to be processed by a series of lathes, drilling machines or grinders after the cold heading machine is used to produce the rivets. Rivets can be surface treated with color zinc plating, blue and white zinc, copper plating, and chrome plating according to the specific requirements of customers. According to the shape of its head, semi-hollow rivets have semi-circular head, flat head, flat head hexagon and other categories.
