||SIMPSON STRONG-TIE SEISMIC & HURRICANE TIE (PRICED PER EACH)
The Hurricane Tie series features various configurations of wind and seismic ties for trusses and rafters.
The NEW H10S provides a high capacity connection from truss/rafter to stud. A flexible nailing pattern allows installation where the stud is offset from the rafter up to 1". Suitable for wood-to-wood and wood-to-CMU/concrete applications.
The H2.5T's truncated design was developed to accommodate trusses with 2x4 bottom chords. The easy to install, five nail pattern is stronger and gets better uplift loads than our popular H2.5 hurricane tie.
The H14 is the high uplift hurricane tie. It can be installed with rafter nailing flanges facing inwards or outwards.
The H2.5A is designed for easy installation, with higher uplift loads to meet new code requirements.
The H16-2 series has a presloped seat of 5:12 for double trusses.
The presloped 5/12 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".
The HGA10 attaches to gable trusses and provides good lateral wind resistance. 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.

Considerations for Hurricane Tie Selection
- What is the uplift load?
- What is the parallel-to-plate load?
- What is the perpendicular-to-plate load?
- What is the species of wood used for the rafter and the top plates?
(Select the load table based on the lowest performing species of wood.)
- Will the hurricane tie be nailed into both top plates or the upper top plate only?
- What load or loads will the hurricane tie be taking?·
- Select hurricane tie based on performance, application, installed cost and ease of installation.
These general instructions for the installer are provided to ensure proper selection and installation of Simpson Strong-Tie Company Inc. products and must be followed carefully. These general instructions are in addition to the specific installation instructions and notes provided for each particular product, all of which should be consulted prior to and during installation of Simpson Strong-Tie Company Inc. products.
- All specified fasteners must be installed according to the instructions in this catalog. Incorrect fastener quantity, size, type, material, or finish may cause the connection to fail.
- 16d fasteners are common nails (0.162" dia. x 3 1/2" long) and cannot be replaced with 16d sinkers (0.148" dia. x 3 1/4" long) for full load value unless otherwise specified.
- Screws may not be used to replace nails in connectors.
- When using stainless steel connectors, use stainless steel fasteners. When using ZMAX®/HDG galvanized connectors, use fasteners galvanized per ASTM A153.
- Fill all fastener holes as specified in the installation instructions for that product. Refer to Simpson’s Fastener Guide for the requirements of the various shaped fastener holes.
- Do not overdrive nails. Overdriven nails reduce shear capacity.
- Use the materials specified in the installation instructions. Substitution of or failure to use specified materials may cause the connection to fail.
- Do not add fastener holes or otherwise modify Simpson Strong-Tie Company Inc. products. The performance of modified products may be substantially weakened. Simpson will not warrant or guarantee the performance of such modified products.
- Install products in the position specified in the catalog.
- Do not alter installation procedures from those set forth in this catalog.
- The proper use of certain products requires that the product be bent. For those products, installers must not bend the product more than one time (one full cycle).
- Bolt holes shall be at least a minimum of 1/32" and no more than a maximum of 1/16" larger than the bolt diameter (per the 2001 NDS, section 11.1.2. and AISI NASPEC, section E3a if applicable).
- Install all specified fasteners before loading the connection.
- Some hardened fasteners may have premature failure if exposed to moisture. The fasteners are recommended to be used in dry interior applications.
- Use proper safety equipment.
- Welding galvanized steel may produce harmful fumes; follow proper welding procedures and safety precautions. Welding should be in accordance with A.W.S. (American Welding Society) standards. Unless otherwise noted Simpson connectors cannot be welded.
- Pneumatic or powder-actuated fasteners may deflect and injure the operator or others. Pneumatic nail tools may be used to install connectors, provided the correct quantity and type of nails (length and diameter) are properly installed in the nail holes. Tools with nail hole-locating mechanisms should be used. Follow the manufacturer’s instructions and use the appropriate safety equipment. Overdriving nails may reduce allowable loads.. Powder-actuated fasteners should not be used to install connectors.
- Joist shall bear completely on the connector seat, and the gap between the joist end and the header shall not exceed 1/8” per ICC-ES AC261 and ASTM D1761 test standards.
- For holdowns, anchor bolt nuts should be finger-tight plus 1/3 to 1/2 turn with a hand wrench, with consideration given to possible future wood shrinkage. Care should be taken to not over-torque the nut. Impact wrenches should not be used as they may preload the holdown.
- Holdowns and HTT tension ties may be raised off the sill when specified by the designer. They may also be raised as dictated by field conditions to accommodate a mislocated anchor bolt provided that: 1) the holdown is not raised more than 18" from the top of the concrete, 2) the anchor bolt is offset no more than 1 1/2" from the centerline of the holdown, and 3) the holdown is raised at least 3" for each 1/4" that the bolt is offset from the centerline of the holdown (anchor bolt slope shall be no greater than 1:12). Some products have increased deflection or load reductions when raised off of the sill (see tables and footnotes of for applicability) and if so the Designer should be contacted for approval.
- Strong-Drive Screws are permitted to be installed through metal truss plates as approved by the Truss Designer, provided the requiremnets of ANSI/TPI 1-2002 Section 8.10 are met (pre-drilling required).
- For cold-formed steel applications to the beginning of, all screws shall be installed in accordance with the screw manufacturer’s recommendations. All screws shall penetrate and protrude through the joined materials a minimum of 3 full exposed threads per AISI Standard for Cold Formed Steel Framing - General Provisions, section D1.3, if applicable.
- Do not weld products listed in this catalog unless this publication specifically identifies a product as acceptable for welding, or unless specific approval for welding is provided in writing by Simpson. Some steels have poor weldability and a tendency to crack when welded. Cracked steel will not carry load and must be replaced.
