Load Tables

  1. Loads have been increased for wind or earthquake loading with no further increase allowed. Reduce where other loads govern.
  2. Allowable loads are for one anchor. A minimum rafter thickness of 2 1/2" must be used when framing anchors are installed on each side of the joist and on the same side of the plate.
  3. Minimum f'c = 2,500 psi and minimum f'm = 1,500 psi.
  4. The HM9KT and HGAM10KTA are kits with (20) HM9 and (10) HGAM10 connectors packaged with Simpson Strong-Tie Strong-Drive® SDS Heavy-Duty Connector screws and 2 1/4" and 2 3/4" Titen® 2 screws, respectively. (1 3/4" Titen® 2 screws for concrete installations sold separately.)
  5. See Titen® 2 screw information
  6. Products shall be installed such that the Titen 2 screws and Titen HD® anchors are not exposed to the weather.
  7. HGAM10 F2 loads are for forces into the connector. See illustration 2 "HGAM10 Installed into Masonry" for loads away from the connector.
  8. LTA2 allowable uplift on SP is 1,425 lb. for perpendicular to wall installation and 1,390 lb. for parallel to wall installation.
  9. Fasteners: 10d x 1 1/2" = 0.148" dia. x 1 1/2" long; 8d x 1 1/2" = 0.131" dia. x 1 1/2" long;
      TTN2-25214H = 1/4" x 2 1/4" Titen 2;
      TTN2-25234H = 1/4" x 2 3/4" Titen 2.
      TTN25214H = Titen 1/4" x 2 1/4" and TTN25234H = Titen 1/4" x 2 3/4" may also be used at full table loads.
