What is a mushroom head square neck bolt, and how does it differ from other bolts?

A mushroom head square neck bolts are fasteners that can be used in construction, manufacturing, and assembly. It has a unique design with a round-shaped head that looks like a small dome of a mushroom and the part called the neck just below the head, which has the shape of a square. That’s why this square-shaped neck is very important; it stops the bolt from turning around at installation, thereby providing more secure connections.

Its distinctive design and practical advantages distinguish them from all other kinds of bolts.
