Countersunk rivets according to DIN 661 or similar are used in various industries such as construction, electrical and electronics industry and mechanical engineering. In these applications, DIN 661 countersunk rivets can create a reliable and durable connection between materials that must withstand high loads and environmental influences. The conical shape of the countersunk rivets also allows for better integration of the rivet heads into the surface of the materials and can therefore be aesthetically pleasing.
