Load Tables

Load Values with Carbon Steel Nails

H/TSP Seismic and Hurricane Ties Load Table
  1. See Straps and Ties General Notes.
  2. Allowable loads are for one anchor. A minimum rafter thickness of 2 1/2” must be used when framing anchors are used on each side of the joist and on the same side of the plate (exception: connectors installed such that nails on opposite side don't interfere).
  3. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members and do not account for possible cross-grain bending of the truss or rafter members.
  4. When cross-grain bending or cross-grain tension cannot be avoided in the members, mechanical reinforcement to resist such forces shall be considered by the designer.
  5. For TSP installed stud to single plate see Stud-Plate Ties.
  6. Fasteners: Nail dimensions in the table are listed diameter by length. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
  7. Using Strong-Drive SD Connector (SD9112) for 0.148” x 1 1/2”, Strong-Drive SD Connector (SD9212) for 0.148” x 2 1/2” (and longer) will get the same load as nails.
