What is a Stud Bolt?

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.

Depending on the Stud bolt material strength they are divided into three groups;

• High-Strength stud bolt
• Intermediate-strength stud bolt, and
• Low-strength stud bolt.

Types of Stud Bolt Threads

Stud bolts use a variety of screw thread profiles depending on the application. Some of the most common thread profiles are:

 

• ISO metric thread
• ACME thread
• UNC thread
• UNF thread
• UN thread
• WHITWORTH thread

Stud Bolt Standards

The design and manufacturing of stud bolts are governed by a range of ASME standards as listed below:

• ASME B16.5 & ASME B16.47 cover the diameter and length.
• ASME B1.1 covers coarse and fine thread series.
• ASME B18.2.1 is used for Square and Hex Bolts and Screws
• ASME B18.2.2 provides details for Square and Hex Nuts
• ASME B18.21.1 provides Lock Washer details
• ASME B18.22.1 is used for Plain Washers

Various other international standards like DIN, ISO, BS, SAE, IS, etc also provide details of stud bolts.

 

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.

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:

 

• Electro zinc plating
• Electro cadmium plating
• PTFE Coating
• Hot-dip galvanizing
• Phosphate coating
• Electroless nickel plating
• Silver coating
• Zinc/Nickel by electrodeposition
• Zinc-nickel coating
• Aluminum coating
• Dacromet
• Geomet
• XYLAN and
• Xylar
