- Minimum embedment depths reflect values for ductile steel failure of the anchor in accordance with ACI 318 for 3000 and 6500 PSI concrete, respectively.
- Use the lesser strength of the outer or inner stud capacity for anchor structural capacity in design.
- For Type C anchor applications, please contact your Williams representative to determine the capacity of the cable hole.
