The A193 B7 Stud Bolt is a versatile fastener designed for use in the Petroleum or Chemical industry. This bolt features threads on both ends, allowing it to be screwed into a fixed part at one end and receive a nut on the other end. The most common application of this stud bolt is in flange connections, where it is used with two nuts on either side, replacing traditional bolt and nut assemblies.
Flange stud bolts, a specific type of stud bolt for flange connections, feature fully threaded bodies with chambered ends. The length of these stud bolts is measured by the thread, providing a secure and reliable connection. Continuous threaded stud bolts are similar to flange stud bolts but lack chambered ends.
Introducing our A193 B7 stud bolt dimensions for ASME B16.5 Class 300 Flanges. These stud bolts are designed to meet the high demands of industries, providing reliable and secure fastening solutions.

A194 Grade 2H Heavy Hex Nuts
Standard A194 covers a variety of carbon steel, alloy steel, and stainless steel nuts designed for high-pressure and high-temperature conditions. These nuts are quenched and tempered carbon steel, undergoing a heat treatment process that enhances hardness. Quenching involves heating, heat preservation, and quick cooling, typically with brine or oil as the cooling medium. Brine provides high hardness but may lead to deformation and cracking, while oil is suitable for stable Austenite carbon steel or Alloy Steel Fittings. Tempering reduces brittleness and internal stress, adjusting mechanical properties to meet various needs. After quenching, heavy hex nuts can be tempered to decrease hardness and increase toughness or plasticity.
