Tack rivets are temporary rivets used to hold pieces of material together during the riveting process.
In essence, they serve as placeholders, ensuring proper alignment and preventing movement before permanent rivets are installed. Think of them as the temporary basting stitches in sewing, holding fabric together before the final seams are sewn.
Here's a breakdown of their purpose and characteristics:
-
Temporary Fastening: Tack rivets are not designed to provide a strong, lasting connection. Their primary function is to maintain alignment during assembly.
-
Easy Removal: Because they are temporary, tack rivets are often easier to remove than permanent rivets. This might involve simply clipping the head off or using a specialized tool.
-
Material: They are typically made of a softer material than permanent rivets, making them easier to deform during installation and removal.
-
Application: They are commonly used in sheet metal work, aircraft construction, and other applications where precise alignment is crucial before permanent fastening.
Why use tack rivets?
- Alignment: They ensure parts are accurately positioned before permanent rivets are set.
- Prevent Movement: They stop pieces from shifting during the riveting process, which is vital for structural integrity.
- Facilitate Assembly: They simplify the assembly process, especially when dealing with large or complex structures.
- Quality Control: They allow for inspection and adjustments before committing to a permanent connection.
In summary, tack rivets are indispensable tools in manufacturing and construction, ensuring accuracy and stability during the riveting process.
