Installation
- Use all specified fasteners.
- Minimum concrete strength is 2,500 psi.
- The allowable loads for bolts are based on parallel to grain loading with a 3″ minimum member thickness, except the HPA which requires a 3-1/2″ thick wood member. Reduce load per code requirements when minimum member thickness is not achieved.
- Minimum concrete end/edge distance is 4″ for PA / PAI series, and 6″ for HPA series.
- Minimum CMU end/edge distance is 20″.
- Designer may specify alternate fastening schedules. Refer to Nail Specification Table Click here for nail shear values. Load values shall not exceed published allowable loads.
- No anchor bolts are needed for achieving efficient stress transfer from framing to concrete walls or foundations.
