- Ultimate load capacities must be reduced by a minimum safety factor 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
- Load capacities can be used with stainless steel anchors and be used as a guide.
