Gangtong Zheli is China manufacturer & supplier who mainly produces ASTM A193 B7 B7M Black Stud Bolt with many years of experience. Hope to build business relationship with you. A stud bolt, also known as a threaded rod or simply a stud, is a long rod with threading on both ends, and the threading can extend along its entire length. Stud bolts are primarily designed to be used in tension, providing a secure connection in various applications. When threaded rods are in the form of bar stock and feature threads along their entire length, they are commonly referred to as all-thread. Studs may have a drive slot on one end, making it easier to install them in place. There are two main types of studs based on their threading configuration: full-bodied studs and undercut studs. Full-bodied studs have a shank that matches the major diameter of the thread, while undercut studs have a shank that corresponds to the pitch diameter of the screw thread. Undercut studs are designed to distribute axial stresses more effectively, reducing the stress concentration found in the threads of full-bodied studs.
ASTM A193 is a specification that covers a range of materials, including alloy steel and stainless steel, for use in pressure vessels, flanges, pipes, fittings, and other components subjected to high temperatures, high pressures, or special applications. This standard includes several grades, such as ferritic steels and austenitic stainless steel, tailored for specific requirements. Material conforming to ASTM A193 B7 is often used with national coarse (UNC) thread pitches and standard thread pitches in various applications where high-strength fasteners are needed.
