Holdowns & Tension TiesLTT/MTT/HTT Tension TiesHoldowns & Tension TiesTension ties offer a solution for resisting tension loads that isfastened with nails. The entire line of tension ties has been tested andevaluated to the requirements of AC155.NEW! The HTT4 and HTT5 are the latest generation of tensionties. They feature an optimized nailing pattern which results inbetter performance with less deflection. Designed to meet newcode standards, the HTT4 and HTT5 offer higher loads than theirpredecessors the HTT16 and HTT22. For an added benefit, theHTT5 installs with 6 fewer nails than the HTT22.The LTT19 Light Tension Tie is designed for 2x joists or purlinsand the LTT20B is for nail- or bolt-on applications. The 3" nail spacingmakes the LTT20B suitable for wood I-joists with 10dx1¹⁄₂. The LTTI31is designed for wood chord open web truss attachments to concrete ormasonry walls and may also be installed vertically on a minimum2x6 stud.MATERIAL: See tableFINISH: Galvanized. May be ordered HDG; contact Simpson Strong-Tie.INSTALLATION: • Use all specified fasteners. See General Notes.• For use in vertical and horizontal applications.• To tie multiple 2x members together, the designer must determinethe fasteners required to join members to act as one unit withoutsplitting the wood. See page 20 for SDS values.• Refer to technical bulletin T-ANCHORSPEC for post-installedanchorage solutions (see page 191 for details).CODES: See page 12 for Code Reference Key Chart.LTTI31LoadtransferplatewashernotrequiredLTT20B(LTT19 similar)AvailableEarly2009HTT5(HTT4 similar)U.S. Patent 5,467,570HTT22(HTT16 similar)U.S. Patent 5,467,570These products are available with additional corrosion protection.

Allowable loads are based on a minimum lumber thickness of 3".4. If a ¹⁄₂" or ⁵⁄₈" anchor bolt is used for the LTT19 or LTT20B, add a standardcut washer to the seat. No additional washer is required for a ³⁄₄" anchor bolt.See table for appropriate anchor bolt sizes.5. If the base of the LTTI31 is installed flush with a concrete or masonry wall,then the allowable load is 2285 lbs.6. Tension values are valid for holdowns flush or raised off of sill plate.7.

The HD19 is a high-capacity bolted holdown designedfor applications that require loads beyond the capacity of the HDUseries holdowns. The HD19 can be installed back-to-back whenmaximum capacity is needed or when eccentricity is an issue.The HD9, HD12 and HD19 holdowns are self-jigging, ensuringthat the code required minimum of seven bolt diameters from theend of the post is met. The HD5 and 7 must be raised such that theseven bolt diameter minimum from the end of the post is maintained.MATERIAL: See table FINISH: Simpson Strong-Tie ® gray paintINSTALLATION: • Use all specified fasteners. See General Notes.• For use in vertical and horizontal applications.• HD holdowns are required to be installed such that thebottom stud bolt is a minimum of seven bolt diameters fromthe end of the post (2005 NDS, Section 11.5.1) which isindicated by the dimension in the drawing labeled (HB). HD9,12 and 19 holdowns are self-jigging, ensuring that the coderequired minimum of seven bolt diameters from the end ofthe post is met. The HD5 and 7 must be raised such that theseven bolt diameter minimum from the end of the post ismaintained (refer to table for HB dimension).• Bolt holes shall be a minimum of ¹⁄₃₂" to a maximum of ¹⁄₁₆"larger than the bolt diameter (per NDS, section 11.1.2).• Standard cut washer required between nut and base whenusing smaller diameter anchor bolts (see footnote 11).• Stud bolts should be snugly tightened with standard cutwashers between the wood and nut (BP’s are required inthe City of Los Angeles).• The Designer must specify anchor bolt type, length, andembedment. See SB and SSTB Anchor bolts (pages 27-29).• To tie multiple 2x members together, the Designermust determine the fasteners required to join membersto act as one unit without splitting the wood (see page20 for SDS values).• Refer to technical bulletin T-ANCHORSPEC for postinstalledanchorage solutions (see page 191 for details).CODES: See page 12 for Code Reference Key Chart.ModelNo.Allowable loads for HDA Holdowns have traditionally been limited by the calculated value of their stud bolts.Preliminary testing to the new acceptance criteria for testing and evaluating holdowns (AC 155) indicatesthat the ultimate capacity divided by a factor of safety exceeds the previously calculated values; however,the allowable loads are limited by deflection under the new critieria. Since significantly lower deflectionsare obtained with comparable SDS-style holdowns we recommend the use of the HDU series of holdowns(see page 37). For those conditions which necessitate a bolted holdown our existing HD product lineprovides the best alternative for high loads at low deflection.Material (Ga) Dimensions Fasteners1. Allowable loads have been increased for earthquake or wind load durations withno further increase allowed; reduce where other load durations govern.2. HD12 and HD19 require a minimum 4x8 (in a 3¹⁄₂" wide shearwall) or 6x6 nominalpost to ensure the tension load carrying capacity of the critical net section meetsthe holdown capacity. Designer to evaluate combined bending and tension stresses.3. HB is the required minimum distance from the end of the stud to the center ofthe first stud bolt hole. End distance may be increased as necessary for installation(see General Notes). Tension values are valid for holdowns installed flush to, orraised off of, the sill plate provided that the minimum HB distance is maintained.4. The Designer must specify anchor bolt type, length and embedment.See SB and SSTB Anchor Bolts (pages 27-29). Refer to technical bulletinT-ANCHORSPEC for retrofit anchor solutions (see page 191 for details).5. Lag bolts will not develop the listed loads.6.
