Which of the following resources would provide the specifications for tightening connection bolts?

• A. OSHA
• B. AISC
• C. ANSI
• D. ASME

Answer: (B)

The main idea is understanding who provides the standards for how bolts in structural steel connections should be tightened. The American Institute of Steel Construction (AISC) publishes the official specifications for structural joints, including how bolts are installed, pretensioned, lubricated, and torqued to achieve the required tension. That guidance directly governs connection bolt tightening in steel frames. OSHA focuses on worker safety practices, not the technical bolt-tightening requirements. ANSI offers general standards across many fields, not the specific structural-connection tightening details. ASME concentrates on mechanical and pressure‑related codes, not typical structural steel connections. So, the resource that provides the tightening specifications for connection bolts is AISC.
