Which option accurately states the maximum spacing for foundation bolts securing plates or sills?

• A. 72 inches
• B. 32 inches
• C. 96 inches
• D. 48 inches

Answer: (A)

Foundation bolts tied to the sill plate create the essential load path from the structure into the foundation, resisting uplift and keeping the wall anchored along its length. The spacing must not exceed a set maximum to ensure the plate cannot lift or shift between bolts under wind, seismic, or other forces. The standard maximum spacing is 72 inches (6 feet) on center, which is why this option is the best choice. Spacing shorter than that is permitted but not the maximum, while a distance of 96 inches would exceed the limit and could allow movement between bolts.
