What marking is specified on studs for high-temperature service?

• A. Marked B16
• B. Marked B8
• C. Marked B12
• D. Marked B36

Answer: (A)

Understanding markings on studs is about recognizing what standard they conform to for a given service. When a stud is marked with B16, it signals compliance with the ASME B16 family of standards, which covers piping components used in high-temperature and pressurized service. This marking indicates the stud has been manufactured and tested to the requirements that ensure suitable strength, dimensional tolerances, and material properties for hot operating conditions, and it helps ensure compatibility with other B16-rated parts in the system. Other markings point to different standards or general fastener categories that don’t specifically certify suitability for high-temperature piping applications, so they aren’t the appropriate indicator for high-temperature service.
