Head Type: Cylindrical Head/Pan Head: Most of the screws at the top and bottom have cylindrical heads with hexagonal recesses, commonly known as socket head cap screws.
Countersunk Head/Flat Head: A small number of countersunk screws (also called flat head socket screws) are mixed in with the scattered screws at the bottom. Their heads are conical and sit flush with the mounting surface after installation.
Hex socket head screws are widely used in industrial manufacturing, furniture assembly, bicycle components (such as water bottle cage screws), and remote-controlled model car parts, and are suitable for various indoor and outdoor applications.
