Simpson Strong-Tie HD9B Holdown only the HD9B is offered here additional items at 25.00 plus 5.00 shipping each Simpson Strong-Tie offers a wide variety of bolted holdowns offering lowdeflection performance for a range of load requirements. All of these holdowns have been tested in accordance with ICC-ES's AC 155 acceptance criteria and are approved for use in vertical and horizontal applications. The HD5B, HD7B and HD9B bolted holdowns incorporate the proven design of our HDQ8 SDS-style holdown and feature a unique seat design which greatly minimizes deflection under load. HDB holdowns are self jigging, ensuring that the code-required minimum of seven bolt diameters from the end of the post is met. They can be installed directly on the sill plate or raised above it and are suitable for back-to-back applications where eccentricity is a concern. HDBs are designed to provide loads for intermediate-load-range shearwalls, braced-wall panels and lateral applications. HD holdowns offer the highest allowable loads, providing high capacity for both vertical and horizontal applications. The HD12 and HD19 are self jigging, ensuring that the code-required minimum of seven bolt diameters from the end of the post is met. They can be installed back-to-back when eccentricity is an issue. Material: See table Finish: HD3B/HD5B/HD7B/HD9B – Galvanized; some models available in HDG HD – Simpson Strong-Tie® gray paint Installation: Use all specified fasteners. See General Notes. 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). Stud bolts should be snugly tightened with standard cut washers between the wood and nut (BP's are required in the City and County of Los Angeles). The Designer must specify anchor bolt type, length, and embedment. See SB and SSTB Anchor bolts. To tie multiple 2x members together, the Designer must determine the fasteners required to join members to act as one unit without splitting the wood Allowable loads have been increased for wind or earthquake with no further increase allowed: reduce where other loads govern. Post design by Specifier. Tabulated loads are based on 3 1/2" wide member minimum, unless noted otherwise. Post may consist of multiple members provided they are connected independently of the holdown fasteners. See Post Capacities for common post allowable loads. Structural composite lumber columns have sides that show either the wide face or the edges of the lumber strands/veneers. Values in the tables reflect installation into the wide face. See technical bulletin T-C-SCLCLM for values on the narrow face (edge). HD and HDB holdowns are self-jigging and will ensure minumum bolt end distance, HB, when installed flush with the sill plate. Deflection at Highest Allowable Tension Load includes fastener slip holdown deformation, and anchor bolt elongation for holdowns installed up to 6" above top of concrete. Holdowns may be installed raised up to 18" above top of concrete with no load reduction provided that additional elongation of the anchor rod is accounted for. To achieve published loads, machine bolts shall be installed with the nut on the opposite side of the holdown. If reversed, the Designer shall reduce the allowable loads shown per NDS requirements when bolt threads are in the shear plane. Lag bolts will not develop the listed loads. Tabulated values may be doubled when the HD holdown is installed on opposite sides of the wood member. The Designer must evaluate the capacity of the wood member and the anchorage. Standard cut washer is required under anchor nut for HD12 with 1" anchor and HD19 with 1 1/8" anchors.
