Which of the following is included in NSC's five items for a link-by-link inspection?

• A. Bent Links
• B. Cracks in weld areas
• C. Transverse nicks or gouges
• D. All of the above

Answer: (D)

Inspection looks for defect types that indicate compromised chain integrity. Bent links show deformation that weakens the cross-section and can lead to failure under load. Cracks in weld areas reveal flaws where the chain is joined and where cracks can propagate with use. Transverse nicks or gouges indicate surface damage that can act as stress risers and initiate failure. The NSC five-item framework specifically includes these kinds of defects, covering deformation, cracks, and surface damage. Since each of these is part of the official inspection criteria, the option that encompasses all of them is the best choice. If you find any of these issues, the chain should be removed from service and evaluated or replaced.
