Hurricane Ties for Plated Truss

This product's information may differ depending on the category of use. You are currently viewing details related to Hurricane Ties for Plated Truss. You can also view product information related to the categories of: Seismic and Hurricane Ties, Hurricane Ties for Masonry, Roof Truss and Rafter Connectors, Ties, and Straps for Cold-Formed Steel Construction

The hurricane tie series features various configurations of wind and seismic ties for trusses and rafters.

H16 — the H16 series has a presloped seat of 5/12 for double trusses. The presloped seat of the H16 provides for a tight fit and reduced deflection. The strap length provides for various truss height up to a maximum of 13 1/2" (H16 series). Minimum heel height for H16 series is 4".

HGA10 — the HGA10 attaches to gable trusses and provides good lateral wind resistance.

HS24 — the HS24 attaches the bottom chord of a truss or rafter at pitches from 0/12 to 4/12 to double 2x4 top plates. Double-shear nailing allows for higher lateral resistance.

Material

  • See table

Finish

  • Galvanized. Some models available in stainless steel or ZMAX® coating. See Corrosion Information.

Installation

  • Use all specified fasteners; see General Notes.
  • Hurricane ties can be installed with flanges facing inward or outward.
  • H2.5T, H 3 and H6 ties are shipped in equal quantities of right and left versions (right versions shown).
  • Hurricane ties do not replace solid blocking.
  • When installing ties on plated trusses (on the side opposite the truss plate) do not fasten through the truss plate from behind. This can force the truss plate off of the truss and compromise truss performance.
  • H10A optional nailing to connect shear blocking, use 0.131" x 2 1/2" nails. Slots allow maximum field bending up to a pitch of 6:12, use H10A sloped loads for field-bent installation.
  • HS24 requires slant nailing only when bottom chord of truss or rafter has no slope.
  • See also H seismic and hurricane ties for masonry applications.

Ordering Information

  • HGA10KT: sold as a kit with (10) HGA10 connectors. Strong-Drive® SDS Heavy-Duty Connector screws are included.
  • Additional screws sold separately to install with all SDS25112 screws.

H/TSP Seismic and Hurricane Ties Load Table
  1. See General Notes for Straps and Ties.
  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 DF/SP uplift load for stud-to-bottom plate installation (see detail 15) is 390 lb. (H2.5A); 265 lb. (H2.5ASS); and 310 lb. (H8). For SPF/HF values, multiply these values by 0.86.
  4. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or cross-grain bending of the truss or rafter members.
  5. 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.
  6. Hurricane ties are shown on the outside of the wall for clarity and assume a minimum overhang of 3 1/2". Installation on the inside of the wall is acceptable (see General Instructions for the Installer, note "p" on p. 18). For uplift continuous load path, install connectors in the same area (e.g., truss-to-plate connector and plate-to-stud connector) on the same side of the wall, unless detailed by designer. See technical bulletin T-C-HTIECON for more information.
  7. Southern pine allowable uplift loads for H10A = 1,340 lb. and for the H14 = 1,465 lb.
  8. Refer to Simpson Strong-Tie® technical bulletin T-C-HTIEBEAR for allowable bearing enhancement loads.
  9. H10S can have the stud offset a maximum of 1" from the rafter (center to center) for a reduced uplift of 890 lb. (DF/SP) and 765 lb. (SPF).
  10. H10S nails to plates are optional for uplift but required for lateral loads.
  11. Some load values for the stainless-steel connectors shown here are lower than those for the carbon-steel versions. Ongoing test programs have shown this also to be the case with other stainless-steel connectors in the product line that are installed with nails. Visit General Corrosion Risks for updated information.
  12. The allowable loads of stainless-steel connectors match carbon-steel connectors when installed with stainless-steel Strong-Drive® SCNR Ring-Shank Connector nails. For more information, refer to engineering letter L-F-SSNAILS.
  13. Allowable DF/SP/SPF uplift load for the H2.5A fastened to a 2x4 truss bottom chord and double top plates using (5) 0.131" x 1 1/2" nails in the top plates and (3) 0.131" x 1 1/2" nails in the lowest three flange holes into the truss bottom chord is 260 lb. (160).
  14. For TSP installed stud to single plate see Stud-Plate Ties.
  15. 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.

  2. 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.
  3. HS24 DF/SP allowable loads without slant nailing are 605 lb. (uplift), 590 lb. (F1), 640 lb. (F2). For SPF/HF loads multiply these values by 0.86.
  4. Allowable loads in the F1 direction are not intended to replace diaphragm boundary members or prevent cross-grain bending of the truss or rafter members. Additional shear transfer elements shall be considered where there may be effects of cross-grain bending or tension.
  5. Fasteners: Nail dimensions in the table are diameter by length. SDS screws are Simpson Strong-Tie® Strong-Drive® screws. For additional information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
