( HEXAGON DOMED CAP NUTS ) 

Unlike classic loaves, one side is open and the other side is closed. They are used to ensure that the bolt tip is not exposed in any combination. The closed face is usually curved outwards in a hemispherical shape. This section also hides the bolt head and provides a more secure finish.

Upon request, surface coating applications such as electro galvanization, zinc nickel, phosphate (black), hot dip galvanization and dacromet/geomet are made.
