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".

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.

H10S — The H10S provides a high-capacity connection from truss/rafter to wall. Also suitable for wood-to-wood applications.

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

HM9 — The HM9 is designed to retrofit roof truss/rafters for block construction. The HM9 hurricane tie provides high uplift and lateral capacity using Simpson Strong-Tie^® Titen^® 2 concrete and masonry screws.

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 do not replace solid blocking.
• H1 can be installed with flanges facing inwards (reverse of H1 drawing).
• 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 8d 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.

Concrete and Masonry Application:

• Connectors attached using hex-head Simpson Strong-Tie^® Titen^® screws.
• Attach to grouted concrete block with a minimum one #5 rebar horizontal in the course.

Options

• H2.5T, H3 and H6 ties are shipped in equal quantities of right and left versions.
• HGA10KT: sold as a kit with (10) HGA10 connectors. Simpson Strong-Tie^® Strong-Drive^® SDS Heavy-Duty Connector screws are included.
• Additional screws sold separately to install with all SDS25112 screws.

    These products are available with additional corrosion protection. Additional products on this page may also be available with this option, check with Simpson Strong-Tie for details.

   These models are approved for installation with the Strong-Drive® SD Connector screw. See the load values below.

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 used on each side of the joist and on the same side of the plate (exeption: 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 may be considered.
6. Hurricane Ties are shown installed 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 notes u). For uplift continuous load path, connections in the same area (i.e. truss to plate connector and plate to stud connector) must be on same side of the wall. See T-HTIECONPATH for more information.
7. Southern Pine allowable uplift loads for H10A = 1,340 lbs. and for H14 = 1,465 lbs.
8. Refer to Simpson Strong-Tie® technical bulletin T-HTIEBEARING for allowable bearing enhancement loads.
9. H10S can have the stud offset a maximum of 1" from rafter (center to center) for a reduced uplift of 890 lbs. (DF/SP), and 765 lbs. (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 to also be the case with other stainless-steel connectors in the product line that are installed with nails. Visit strongtie.com/corrosion for updated information.
12. The allowable loads of stainless-steel connectors match carbon-steel connectors when installed with Simpson Strong-Tie® stainless-steel, SCNR ring-shank 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) 8d x 1 1/2" nails into the top plates and (3) 8d x 1 1/2" nails into the lowest three flange holes into the truss bottom chord is 260 lb. (160).
14. NAILS: 16d x 2 1/2" = 0.162" dia. x 2 1/2" long, 10d = 0.148" dia. x 3" long, 10d x 1 1/2" = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8d x 1 1/2" = 0.131" dia. x 1 1/2" long. See other nail sizes and information.
    SCREWS: Strong-Drive® SD #9x1 1/2" (model SD9112) = 0.131" dia. x 1 1/2" long (for the models marked with the orange flag only). Full table loads apply.

HS24 Installation

HGA10 Installation to Double Top Plates

1. Loads have been increased for wind or earthquake loading with no further increase allowed; reduce where other loads govern.
2. When cross-grain bending or cross-grain tension cannot be avoided, mechanical reinforcement to resist such forces should be considered.
3. HS24 DF/SP allowable loads without slant nailing are 605 lbs. (uplift), 590 lbs. (F₁), 640 lbs (F₂). For SPF/HF loads multiply these values by 0.86.
4. For H16-2S, S = short.
5. 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.
6. HGA10 loads in table are for when truss is perpendicular to the wall. If truss is parallel with wall, then uplift is 695 lb., F₁ is 925 lb. and F₂ is 780 lb. for DF/SP. For SPF/HF, multiply load values by 0.72.
7. NAILS: 10d x 1 1/2" = 0.148" dia. x 1 1/2" long, 8d = 0.131" dia. x 2 1/2" long, 8d x 1 1/2" = 0.131" dia. x 1 1/2" long.
   See other nail sizes and information.
