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.
Types of Stud Bolts
Depending on the threading pattern and design, various types of stud bolts are available as listed below:
* Fully threaded stud bolt or continuous threaded stud bolt having uniform thread throughout its length.
* Tap end stud bolts having unequal threads from each end and non-threaded center.
* Double-end stud bolts having both ends threaded of equal lengths and a non-threaded center.
* Flange Stud bolts: Fully threaded stud bolts with chamfered ends specifically used for flanged connections.
* Double-end stud bolt with reduced shank: the non-threaded center part is of a reduced diameter than the actual diameter.
Stud Bolt Materials
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:
* ASTM A354 Gr BC, BD
* ASTM A540 Gr B21 to B24
* ASTM A193 Gr B5, B6, B8, B16, B8M, B8A, B8T, L7, B17B.
* ASTM A453 Gr 660A/B/C/D
* ASTM A913 Inconel 718
* ASTM A320 Gr L7M, L43, B8, B8A, B8T, B8MA, B8C
* ASTM A182 Gr S31803, S32205.
