Explanation:

  • The following are the tools generally used in hand-riveting:
    • Riveting set: It is used for bringing the plates closely together after inserting the rivet in the hole.
    • Dolly: It is used to support the head of the rivet which is already formed and also to prevent damage to the shape of the rivet head.
    • Rivet snap: It is used to form the final shape of the rivet during riveting. Rivet snaps are available to match the different shapes of rivet heads.
    • Drift: It is used to align the holes to be riveted.
    • Caulking tool: It is used for closing down the edges of the plates and heads of the rivets to form a metal-to-metal joint.
    • Fullering tool: It is used for pressing the surface of the edge of the plate. It helps to make fluid-tight joints.
