- Ultimate load capacities must be reduced by a minimum factor of safety of 4.0 to determine allowable loads.
- Consideration of safety factors of 10 or higher may be necessary depending on application, such as life safety or overhead.
- Tabulated load values are for anchors installed in uncracked concrete.
- The concrete compressive strength must be at the specified minimum at the time of installation.
- To determine which grade of stainless steel may be more appropriate for your application, please consult a design professional.
