Which statement best defines rivet grip?

• A. The diameter of the rivet shank.
• B. The total thickness of the material riveted by the rivet.
• C. The ornamental cap size.
• D. The heat treatment of the rivet.

Answer: (B)

Rivet grip is the total thickness of the material the rivet is designed to join in one operation. It tells you how much material the rivet shank must pass through and how long the rivet needs to be to form a proper head on the tail side. This is why grip directly determines rivet length selection: the rivet must be long enough to fill the material stack but not so long that it overflows or damages the joint. The diameter of the rivet shank, heat treatment, or decorative cap size are separate considerations and do not define grip.
