What is the rule of thumb for spacing between concrete fasteners?

• A. 8 anchor diameters
• B. 10 anchor diameters
• C. 12 anchor diameters
• D. 15 anchor diameters

Answer: (B)

The guideline for spacing between concrete fasteners suggests using a distance of 10 anchor diameters, which ensures adequate load distribution and maintains the integrity of the surrounding concrete. This spacing helps prevent issues related to rebar interference, concrete spalling, or weakening of the material, which can occur if anchors are placed too closely together. By adhering to this rule, you help ensure that the fasteners can perform effectively without compromising the structural integrity of the concrete.

Choosing a distance that is either too small or excessively large can lead to either structural failures or inefficient use of the materials, making the 10 anchor diameters rule a practical standard in construction practices.
