Which characteristic is NOT true regarding the performance of a DD rivet?

The understanding of DD rivets involves recognizing their unique properties in comparison to standard rivets. The assertion that it is more difficult to install than a standard rivet is not accurate; in fact, the design and material properties of DD rivets often allow for easier installation under certain conditions.

DD rivets are specifically designed to achieve high strength after installation while maintaining a level of softness immediately post-heat treatment, which aids in the riveting process. This characteristic ensures that they can be deformed easily during installation, making it simpler to achieve a secure fit without applying excess force.

Additionally, DD rivets actually provide exceptional strength once fully installed, which is why they are often the preferred choice in applications requiring reliable structural integrity. They are engineered to require less force during installation compared to conventional rivets, allowing for efficiency in the riveting process.

Thus, the characteristics of DD rivets portray them as advantageous in many situations, which is why the statement about them being more challenging to install than standard rivets does not hold true.
