EFFECTS Wind forces are generated from natural events like thunderstorms, hurricanes and tornadoes These winds create forces that attack the integrity of a structure in multiple ways: vertically, resulting in uplift forces, and horizontally, resulting in overturning, sliding and racking forces Without proper design and construction, these forces can produce structural damage and even destruction Modern design and construction practices, such as structural connectors used in a continuous load path transfer system, can effectively resist these forces by reinforcing the structure from the roof to the foundation CS H10A When wind blows against the side of the structure exerting a lateral force that causes it to lean over (rack) to one side SPH4 TSP Strong-Wall® Shearwall Steel

modifications, improper loading, installation procedures, or deviations from recommended applications will affect connector allowable load-carrying capacities High Wind-Resistant Construction NEW PRODUCTS DETAL Truss Anchor The DETAL high-capacity embedded truss anchor attaches single-ply roof trusses to concrete and masonry walls The DETAL20 combines dual embedded anchors with a structural moisture-barrier plate to protect the truss and provide increased lateral capacity in addition to exceptional uplift loads FSC Floor Span Connector As an alternative to coil strap, the FSC connects the upper floors to lower floors from the inside of the wall The convenient obround holes make installation in narrow wall cavities easy Installs to studs with nails and through the floor system with a ³⁄₈" threaded rod, a nut and a washer (not included) H2A Hurricane Tie H10A Hurricane Tie The new H10A hurricane tie attaches to double top plates and provides up to 1340 lbs of uplift capacity when attached to an SP truss Nearly as much uplift capacity as the H14, yet lower cost and easier to install H10S Hurricane Tie The H10S provides a high capacity connection from the truss/rafter to the 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 C-HW09 © 2009 SIMPSON STRONG-TIE COMPANY INC The new H2A is an improved version of the H2 hurricane tie with up to 575 lbs of uplift capacity Minimal nailing into the top plates eases installation while contributing to the uplift capacity High Wind-Resistant Construction NEW PRODUCTS HTT4 & HTT5 Tension Ties The LTT/MTT/HTT series of tension ties offers tension-resisting solutions that install with nails These new additions to the HTT line feature an optimized nailing pattern which results in better performance with less deflection Designed to meet new code standards, the HTT4 and HTT5 offer higher loads than their predecessors the HTT16 and HTT22 For an added benefit, the HTT5 installs with fewer nails than the HTT22 LGT3-SDS2.5/LGT4-SDS3 Girder Tiedown With over 3,200 lbs of uplift, the LGT3-SDS2.5 and LGT4-SDS3 are high capacity girder tiedowns for girder trusses with three and four plies, respectively These tiedowns not require attachment to the top of the truss, allowing installation after the roof is sheathed They attach to the truss with Simpson Strong-Tie® Strong-Drive® screws (SDS) for higher load capacity, and a low-profile connection to the studs ensures easy installation of drywall The LGT3-SDS2.5 and LGT4-SDS3 can be installed on the inside or outside of walls and provide additional bearing enhancement for heavy download applications MASA Mudsill Anchor C-HW09 © 2009 SIMPSON STRONG-TIE COMPANY INC MAS mudsill anchors have always been a time-saving alternative to mudsill anchor bolts, and now the new and improved design of the MASA provides for one-to-one replacement of ¹⁄₂" and ⁵⁄₈" anchor bolts in 2x sill plates Additional fasteners and the reinforcement of key sections of the anchor have improved performance so that the load capacity of the MASA mudsill anchor either meets or exceeds that of other cast-in-place anchors Since the MASA can be installed as wide as 6' on center, the same load capacity can be achieved with fewer mudsill anchors TSP Twist Stud Plate The TSP offers higher loads in a tie that fastens on the side of the stud to reduce interference with drywall installation Suitable for both top-plate and sill-plate applications VGT Variable Girder Tiedown The VGT is a higher capacity alternative to the LGT and MGT for girder trusses It attaches with Simpson Strong-Tie Strong-Drive screws (SDS) to the side of the truss and features a predeflected crescent washer that allows it to accommodate top chord pitches up to 8:12 High Wind-Resistant Construction GENERAL NOTES Refer to the current Simpson Strong-Tie® Wood Construction Connectors catalog for connector load values, installation, fastener schedules and other important information including Terms and Conditions of Sale and Building Code Evaluation listings Throughout the catalog there are installation drawings showing the load transfer from one element in the structure to another Additional connections may be required to safely transfer the loads through the structure It is the Designer’s responsibility to specify and detail all necessary connections to ensure that a continuous load path is provided as required by the building code Loads are provided for a 160% load duration increase on the calculated capacity of the nails No further load duration increase is allowed by the building code Load values on every product DO NOT include a one-third increase on the steel capacity Unless otherwise noted, the allowable loads published in this catalog are limited to the lowest of: average recorded test load at ¹⁄₈" deflection, lowest ultimate recorded test load of tests specimens divided by (or the average of specimens divided by 3), or the calculated value based on steel, wood bearing, and/or fastener capacity When multiple connectors are used, they must be installed so fastener locations not overlap Unless otherwise noted, allowable loads are for use with Douglas Fir Larch or Southern Pine lumber Allowable simultaneous loads in more than one direction on a single connector must be evaluated as follows: Design Uplift/Allowable Uplift + Design Lateral Parallel to Plate/Allowable Lateral Parallel to Plate + Design Lateral Perpendicular to Plate/Allowable Lateral Perpendicular to Plate < 1.0 The three terms in the unity equation are due to the three possible directions that exist to generate force on a connector The number of terms that must be considered for simultaneous loading is at the sole discretion of the Designer and is dependent on their method of calculating wind forces and the utilization of the connector within the structural system All references to bolts or MBs are for structural quality through bolts equal to or better than ASTM Standard A307, Grade A Lag bolts and carriage bolts are not acceptable All threaded rod or ATR shall be equal to or better than ASTM A36, Grade C Unless otherwise noted, all nails are common nails (refer to page 10) 10 Refer to Simpson Strong-Tie technical bulletin

hereby expressly excluded This warranty may change periodically – consult our website www.strongtie.com for current information CORROSION INFORMATION Understanding the Issues Metal connectors, anchors, and fasteners will corrode and may lose loadcarrying capacity when installed in corrosive environments or exposed to corrosive materials There are many environments and materials which may cause corrosion including ocean salt air, fire retardants, fumes, fertilizers, preservative-treated wood, dissimilar metals, and other corrosive elements The many variables present in a single building environment make it impossible to accurately predict if, or when, significant corrosion will begin or reach a critical level This relative uncertainty makes it crucial that specifiers and users be knowledgeable of the potential risks and select a product coating or metal suitable for the intended use It is also important that regular maintenance and periodic inspections are performed, especially for outdoor applications It is common to see some corrosion on connectors especially in outdoor applications Even stainless steel can corrode The presence of some corrosion does not mean that load capacity has necessarily been affected or that a failure will occur If significant corrosion is apparent or suspected, then the wood, fasteners and connectors should be inspected by a professional engineer or general contractor and may need to be replaced In the last several years, preservative-treated wood formulations have changed significantly Many of the new formulations are more corrosive to steel connectors and fasteners than the traditionally used formulation of CCA-C Simpson Strong-Tie testing has shown that ACQ-C, ACQ-D (Carbonate), CBA-A and CA-B treated woods are approximately times more corrosive than CCA-C, while SBX-DOT (Sodium Borate) treated woods were shown to be less corrosive than CCA-C Refer to technical bulletin T-PTWOOD for more information Due to the many different preservative formulations, fluctuating retention levels, moisture content, and because the formulations may vary regionally, or change without warning, understanding which connectors and fasteners to use with these materials has become a complex task We have attempted to provide basic knowledge on the subject here, but it is important to fully educate yourself by reviewing our technical bulletins on the topic, and also by viewing information and literature provided by others This information pertains to Simpson Strong-Tie® connectors only For corrosion information on other product lines, such as fasteners, see the specific Simpson Strong-Tie product line catalogs Additionally, because the issue is evolving, it is important to get the very latest connector information on the topic by visiting our website at www.strongtie.com/info Stainless steel is always the most effective solution to corrosion risk However, it is also more expensive and sometimes more difficult to obtain To best serve our customers, Simpson Strong-Tie is evaluating the options to identify the safest and most cost-effective solutions Based on our testing and experience there are some specific applications that are appropriate for ZMAX/HDG or G90 connectors (see chart on page 9.) Because increased corrosion from some newer preservative-treated wood is a new issue with little historical data, we have to base our recommendations on the testing and experience we have to date It is possible that as we learn more, our recommendations may change, but these recommendations are based on the best information we have at this time C-HW09 © 2009 SIMPSON STRONG-TIE COMPANY INC Simpson Strong-Tie Company Inc warrants catalog products to be free from defects in material or manufacturing Simpson Strong-Tie Company Inc products are further warranted for adequacy of design when used in accordance with design limits in this catalog, and properly specified and installed This warranty does not apply to uses not in compliance with specific applications and installation procedures set forth in this catalog, or to non-catalog or modified products, or to deterioration due to environmental conditions High Wind-Resistant Construction CORROSION INFORMATION General Simpson Strong-Tie Recommendations • Outdoor environments are generally more corrosive to steel If you choose to use ZMAX® or HDG finish on an outdoor project (i.e deck, patio cover), you should periodically inspect your connectors and fasteners or have a professional inspection performed Regular maintenance including waterproofing of the wood used in your outdoor project is also a good practice • For wood with actual retention levels greater than 0.40 pcf for ACQ and MCQ, 0.41 pcf for CBA-A, or 0.21 pcf for CA-B (Ground Contact), stainless-steel connectors and fasteners are recommended Verify actual retention level with the wood treater • When using stainless-steel connectors, use stainless-steel fasteners When using ZMAX/HDG galvanized connectors, use fasteners that meet the specifications of ASTM A153 • Testing indicates wood installed dry reduces potential corrosion If dry wood is used, see our website for additional information • Using a barrier membrane can provide additional corrosion protection, see technical bulletin T-PTBARRIER Due to the many variables involved, Simpson Strong-Tie cannot provide estimates on service life of connectors, anchors or fasteners We suggest that all users and Designers also obtain recommendations for HDG, ZMAX (G185), mechanically galvanized, or other coatings from the treated wood supplier for the type of wood used However, as long as Simpson Strong-Tie recommendations are followed, we stand behind product performance and our standard warranty applies Guidelines for Selecting the Proper Connector Compare the treated-wood supplier’s recommendation Evaluate the Application with the Simpson Strong-Tie recommendation Consider the type of structure and how it will be used These recommendations may not apply to non-structural applications such as fences If these recommendations are different, Simpson Strong-Tie recommends that the most conservative recommendation be followed Evaluate the Environment Simpson Strong-Tie recommendations are as follows: Testing and experience indicate that indoor dry environments are less corrosive than outdoor environments Determining the type of environment where a connector or fastener will be used is an important factor in selecting the most appropriate material and finish for use on the connectors and fasteners To help in your decision making, consider the following general exposure information: Interior Dry Use: Includes wall and ceiling cavities, and raised floor applications of enclosed buildings that have been designed to ensure that condensation and other sources of moisture not develop Exterior – Dry: Includes outdoor installations in low rainfall environments and no regular exposure to moisture Exterior – Wet: Includes outdoor installations in higher moisture and rainfall environments Higher Exposure Use: Includes exposure to ocean-salt air, fire retardants, large bodies of water, fumes, fertilizers, soil, some preservative-treated woods, industrial zones, acid rain, and other corrosive elements Type 316 stainless steel contains slightly more nickel than other grades, plus molybdenum, giving it better corrosion resistance in high-chloride environments Low = Use standard painted and G90 galvanized connectors, or Simpson Strong-Tie® Strong-Drive® screws (SDS) with the double-barrier coating, as a minimum Med = Use ZMAX/HDG galvanized connectors as a minimum Use HDG fasteners which meet the specifications of ASTM A153 or Simpson Strong-Tie® Strong-Drive® screws (SDS) with double-barrier coating High6 = Use Type 303, 304, 305 or 316 stainless-steel connectors and fasteners CONNECTOR COATING RECOMMENDATION – STRUCTURAL APPLICATIONS Environment C-HW09 © 2009 SIMPSON STRONG-TIE COMPANY INC The treated wood supplier should provide all the information needed regarding the wood being used This information should include: the specific type of wood treatment used, if ammonia was used in the treatment, and the chemical retention level If the needed information is not provided then Simpson Strong-Tie would recommend the use of stainless-steel connectors and fasteners You should also ask the treated-wood supplier for a connector coating or material recommendation the chart on the right, which was created based on Use Simpson Strong-Tie testing and experience to select the connector finish or material If a preservative-treated wood product is not identified on the chart, Simpson Strong-Tie has not evaluated test results regarding such product and therefore cannot make any recommendation other than the
