Stud bolt ASTM A193 B8/B8M "Thread to Thread" Class 2A c/w 2 Heavy Hex Nut ASTM A194 Gr.8/8M Class 2B
Finished hex nuts are easily the most prevalent style of nut in the world. They are found in virtually every industrial, structural, construction, or machinery application. They are designed to pair with bolts, screws, studs, or some other externally threaded component. The internal threads of the Finished Hex Nut mate with the external threads of the bolt, creating friction between the opposing threads and tension in the externally threaded component, thereby introducing clamping force between the fastening units. For this reason, it is a solid union with substantial holding force.
