Gangtong Zheli is ASTM A193 B7 B8 B8M B16 B7M Gr8.8 Black Stud Bolt Threaded Rod manufacturers and suppliers in China who can wholesale it. A stud bolt, also referred to as a threaded rod or simply a stud, is a lengthy rod with threads on both ends, extending along its entire length. These threaded rods are designed to be used in tension applications. When these threaded rods are in the form of solid bar stock with threads along their entire length, they are commonly referred to as "all-thread." Stud bolts may feature a drive slot at one end, which facilitates the installation process.
There are two main types of studs based on the extent of their threading: full-bodied studs and undercut studs. Full-bodied studs have a shank that matches the major diameter of the thread. In contrast, undercut studs have a shank that corresponds to the pitch diameter of the screw thread. Undercut studs are engineered to more effectively distribute axial stresses, whereas in full-bodied studs, the stresses are predominantly concentrated in the threaded portions.
