What is the minimum member thickness for adhesive anchors? and Screw anchors
What is the minimum member thickness for adhesive anchors? Can you please describe to me what are the code limitations for thickness?
Should I use the ACI or AC193 limitations?
Thank you for your help

Ahmad,
Typically, for Hilti adhesive anchors with 3/8” and ½” diameter anchor rods, the minimum concrete thickness is hef + 1-1/4”. For larger anchor rod diameter sizes of 5/8”, ¾”, 7/8” 1”, and 1-1/4”, the minimum concrete thickness is hef + 2*do. These specifications can be found in the product technical guide found here. ACI specifications for concrete thickness should be followed in the absence of manufacturer specifications.
