B7 studs are a specific type of studs commonly used in construction and engineering. They are often made of steel and are designed to provide strong and secure fastening in various applications, such as in the assembly of structural components or machinery. The “B7” designation typically refers to a specific grade or standard for these studs, indicating their strength and durability.

ASTM A-193 B7 bolts

ASTM A-193 B7 bolts are built to the requirements of numerous specifications and material design properties. To be more specific, B7 alloy steel is a high temperature grade of A-193. B7 steel is also a chrome moly steel with a minimum tensile strength of 125ksi. Depending on your unique project requirement needs, grade B7 bolts can be used in numerous types of extreme conditions.

Fastener Solutions, Inc. is an industry leading supplier of grade b7 stud bolts. These extremely reliable fastener products are manufactured from advanced quality ASTM A-193 gr B7 materials, which provides them the capabilities to withstand extremely volatile environments.

Grade B7 Bolt Materials

Grade B7 is the most common grade of A-193 B7 alloy steel bolt material that is regularly utilized within the construction industry. ASTM A-193 B7 stud bolts are manufactured from chromium-molybdenum steel and are heat treated to provide increased strength and reliability. We offer these bolts in the following materials:

  • Plain
  • Plated​
  • Coated
b7 coating and plating

B7 Bolt Coatings

ASTM A-193 B7 bolts can also be coated in a wide range of materials, including:

  • Flouropolymer coatings – Xylan and Teflon
  • Molybdenum Disulfide
  • Epoxy Coatings – Thermal cure
  • Phosphate coating – Manganese and Zin

In addition, coated grade B7 bolt studs may not be able to withstand the extreme temperatures that uncoated B7 alloy steel bolts may be able to endure.

What is ASTM A-193?

The Association of Standards & Materials is a governance body that provides specifications for a wide range of materials and fastener types. They also define the policy that obtains and certifies externally threaded fasteners based on certain criteria. ASTM A-193 also oversees specifications of bolting components within a wide range of assemblies, including pressure vessels, piping, valves and more. Additionally, they oversee the functioning capabilities, including the structural limits of fastener devices, which ensures safer job sites and work environments.

Our B7 studs are commonly coated with a fluoropolymer, although we offer a wide range of finishes including clear zinc, yellow cadmium, hot dip galvanized, and more. Our most popular product, B7 studs and nuts coated with a fluoropolymer finish, are considered superior due to their many added performance properties. They are easier to remove after prolonged exposure to corrosive environments since they are produced without the use of nut-locking oxides. This feature ensures excellent corrosion resistance, making them perfect for use in irrigation, chemical plants, refineries, and similar environments where corrosion is a concern.
