What is the stub size calculation for a 1/2" bolt hole?

• A. 3/8
• B. 5/8
• C. 1/4
• D. 7/16

Answer: (A)

The correct calculation for the stub size associated with a 1/2" bolt hole is 3/8". This relationship is based on standard practices in the field, which typically dictate that the stub size should be determined based on a specific formula or guideline that refers to the diameter of the bolt hole. In this case, the size of the stub—used for supporting or reinforcing the connection around the bolt hole—needs to be smaller than the diameter of the bolt to ensure that it provides adequate insertion space while still being structurally sound. Thus, 3/8" is the appropriate choice as it aligns with the calculations developers and engineers use to ensure proper fit and support in piping systems. Understanding these dimensions is crucial for maintaining the integrity of the installation and ensuring safety in mechanical applications, particularly in the pipefitting industry where precision is key.
