H10A Hurricane Tie

The H10A series holds the rafter or truss on both sides for high uplift applications with embossments that add stiffness in crucial areas for improved performance. These U-shaped hurricane ties provide faster installation than using two single-sided ties. H10A models come with optional fastener holes to connect roof blocking to the top plate. Slots allow field bending up to a maximum pitch of 6:12 to accommodate angled blocking.

Key Features

  • Forms part of a continuous load path to resist wind and seismic forces
  • The H10A-2 model holds a double-ply member and is approved for installation with the Strong-Drive® SD Connector screw
  • The H10AR model is designed for rough lumber sizes

Material

  • 18 ga.

Finish

  • Galvanized (G90). Selected products 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.
  • 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.

  1. See Straps and Ties General Notes.
  2. 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.
  3. 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.
  4. Southern pine allowable uplift loads for H10A = 1,105 lb. (160).
  5. 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.
  6. 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.
  7. Simpson Strong-Tie offers stainless-steel Strong-Drive® SCNR Ring-Shank Connector nails. SCNR nails are available in paper-collated strips and in bulk for hand-drive fastening. See general fastener information.
  8. Fasteners: Nail dimensions in the table are listed diameter by length. For general fastener information, see Fastener Types and Sizes Specified for Simpson Strong-Tie Connectors.
  9. Using Strong-Drive SD Connector (SD9112) for 0.131" x 1 1/2" and 0.148" x 1 1/2", Strong-Drive SD Connector (SD9212) for 0.131" x 2 1/2" (and longer) will get the same load as nails.
