Which diameter is outside the specified anchor rod range?

• A. 3/8"
• B. 1/2"
• C. 1"
• D. 2"

Answer: (D)

Understanding anchor rod size limits helps ensure hardware fits correctly and the connection behaves as designed. The specified range for anchor rods constrains diameters so they match the base plate holes, thread engagement, and embedment details used in the project. Within that range, common sizes like three-eighths, one-half, and one inch are typical—they fit standard plates, align with typical bolt patterns, and allow proper installation tolerances. A diameter of two inches is far larger than those standard options and would require oversized holes, a different base plate design, and likely a different fastening approach. Because it exceeds the allowed size for the project’s anchor rods, it sits outside the specified range.
