1.Hex bolts have hexagonal heads, hence their name. They are primarily used in repair and

construction jobs. Hex bolts, also called machine bolts, typically have a smooth portion that

separates the base of the head from the area where the threading begins. During the manufacturing

process, the diameter of the head increases as the length of the bolt increases. Hex bolts are often 

available in large sizes, with a diameter that can reach 2 inches and length of up to 30 inches. These

bolts can have fine or very course threading.

Hexagon head cap screws and bolts are used widely. The hexagon head is designed for easy usage, 

and it performs well in balance between force application and reception. The external appearance of 

these products is to match and to be used together with the internal parts, for example, nuts, and then

to fasten the components.
