HGAM Hurricane Gusset Angle for Masonry


On This Page

The HGAM is designed to secure the bottom chord of a gable end truss or other framing member to masonry. The engineered gusset in the angle increases strength for lateral and uplift loads. This hurricane gusset angle installs easily with 1 1/2" Strong-Drive® SDS Heavy-Duty Connector screws and Titen® 2 masonry screws to concrete or masonry.

Key Features

  • Engineered for increased loads in high-wind or seismic events
  • Also available in kits with Strong-Drive SDS and Titen screws
  • Strong-Drive SDS screws are high-strength structural screws that install with no predrilling because of their patented, easy driving Type-17 point


  • 14 ga.


  • Galvanized


  • Use all specified fasteners; see General Notes
  • Connectors attached using hex-head Titen 2 screws
  • Attach to grout-filled CMU with a minimum one #5 rebar horizontal in the course
  • Hurricane ties do not replace solid blocking

Load Tables

HGAM10 Seismic and Hurricane Ties / Lateral Truss Anchor Load Table
  1. Loads have been increased for wind or earthquake loading, with no further increase allowed. Reduce where other loads govern.
  2. HGAM10KTA 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. Concrete shall have a minimum compressive strength of f'c = 2,500 psi.
  4. Grout-filled CMU (GFCMU) shall have a minimum compressive strength of f'm = 1,500 psi.
  5. The HGAM10KTA is a kit with (10) HGAM10 connectors packaged with Strong-Drive® SDS Heavy-Duty Connector screws and 2 3/4" Titen® 2 screws. 1 3/4" Titen 2 screws for concrete installations sold separately.
  6. See Titen® 2 screw information.
  7. Products shall be installed such that the Titen® 2 screws are not exposed to the weather.
  8. HGAM10 F2 loads are for forces into the connector. F2 loads away from the connector are 640 lb. (DF/SP) and 460 lb. (SPF/HF).
