Fasteners and rivets are mechanical components used to connect and secure two or more parts, and are widely used in aerospace, automotive manufacturing, construction engineering, and electronic products. Fasteners typically provide a removable connection (such as bolts and screws), while rivets create a permanent, non-removable connection through plastic deformation (such as solid rivets and blind rivets). Both have their own characteristics in terms of structural strength, installation methods, and application scenarios, and are fundamental and critical components in mechanical assembly and manufacturing.
