Common rivets Commonly used are semi-circular heads, flat heads, semi-tubular rivets, solid rivets, countersunk rivets, blind rivets, hollow rivets, which are usually riveted by their own deformation connection. (Generally less than 8 mm for cold riveting, larger than for hot riveting.) But there are exceptions, such as the nameplate on the three-ring lock, which is riveted with the interference of the rivet and the lock body hole. Special rivet There are also pairs of rivets, which are special. Divided into two parts, the thicker section of the capped rod body has a hole in the center, and the thinner part of the capped rod body has an interference fit. When riveting, push the thin rod into the thick rod.
