A threaded fastener having an exterior male thread is known as a U bolt. U bolts and screws have a lot in common. GDPA Fasteners is the leading U bolt manufacturer (Hersteller von U-Bolzen) in the competitive market. People are confused about the distinction between screws and U bolts. To create a bolted junction, U bolts are frequently employed. Combining the nut’s axial clamping force with the U bolts’ dowel-like shanks to pin the joint against sideways shear stresses results in this situation. Due to the fact that this result in a superior, stronger dowel, many U bolts feature in plain, unthreaded shank (referred to as the grip length). Unthreaded shanks have frequently been cited as distinguishing features of U bolts over screws however, they are merely incidental to their use rather than defining.
