What are the main parts of semi-permanent fasteners?

The main parts of semi-permanent fasteners typically include the head, grip, and thread.

The head serves as a larger flat area on top of the fastener, providing a surface to apply force or torque when tightening or loosening the fastener. The grip refers to the length of the fastener that actually holds the materials together, making it critical for ensuring structural integrity. The thread is the helical ridge that allows the fastener to be screwed into a material, enabling it to fasten securely.

These components work together to create a robust connection while allowing for the possibility of disassembly as needed, thus defining the functionality of semi-permanent fasteners in various applications.
