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 edge distance is 4" for PA / PAI series, and 6" for HPA series.
  • Minimum concrete block 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.
