What is the primary function of fasteners in assembly applications?

The primary function of fasteners in assembly applications is to join components securely together. Fasteners, such as bolts, screws, nuts, and rivets, create a physical connection between parts, ensuring that they remain in place under various conditions, including movement, vibration, and thermal expansion. This secure joining is critical for maintaining the integrity and functionality of assembled products, whether in machinery, furniture, automotive, or construction applications. By effectively holding components together, fasteners contribute to the overall strength and stability of the assembly, allowing it to perform as intended.

While the aesthetic appeal of products and decoration can be relevant in certain design contexts, these are secondary functions and not the primary goal of fasteners in most assembly scenarios. Similarly, while some fasteners can allow for movement (point of articulation), this is not their main purpose for the majority of applications.
