blind rivets
Blind rivets are fasteners used to join two or more materials together, typically in situations where only one side of the assembly is accessible. They consist of a hollow cylinder with a mandrel inside. When the mandrel is pulled, it deforms the end of the rivet, creating a strong bond without needing access to the opposite side.
These rivets are commonly used in construction, automotive, and aerospace industries due to their ease of installation and reliability. They can be made from various materials, including aluminum, steel, and plastic, making them versatile for different applications.
