For a 25 mm hole drilled in plates to be riveted, the shank diameter of the rivet should be _______________ mm?
Correct answer: B. 23
- A. 25
- B. 23
- C. 26
- D. 27
Explanation
The rivet hole is made slightly larger than the rivet shank to allow insertion and subsequent expansion during riveting. For a 25 mm hole, the standard approximate shank diameter is therefore 23 mm.
