A stud bolt is a mechanical fastener having external threads without a head. The external thread is either for the full length of the stud or partially threaded from each end. It uses at least two nuts, one on each side for assembly connection. Stud bolts are available in various sizes, types, and threading patterns.
Depending on the threading pattern and design, various types of stud bolts are available as listed below:
Depending on the Stud bolt material strength they are divided into three groups;
Stud bolts use a variety of screw thread profiles depending on the application. Some of the most common thread profiles are:
The design and manufacturing of stud bolts are governed by a range of ASME standards as listed below:
Various other international standards like DIN, ISO, BS, SAE, IS, etc also provide details of stud bolts.
For high-temperature and pressure services, ASTM A193 is the most widely used flange material. Grade B7 and B7M are the most frequently used A193 material grades. For low-temperature services, ASTM A320 Gr L7, L7A, and L7B are used. Other stud bolt materials include the following:
The nut and washer material must be compatible with the selected stud-bolt material to avoid galvanic corrosion. Sometimes stud bolts are coated to increase corrosion resistance. The common coating materials are:
