Simpson Hd8qsds3 Vert. Holdowns

The unique seat design of the HDQ8 greatly minimizes deflection under load. This holdown employs Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws, which install easily, reduce fastener slip and provide a greater net section when compared to bolts. It may be installed either flush or raised off the mudsill without a reduction in load value.

• SDS screws are supplied with the holdowns to ensure proper fasteners are used
• No stud bolts to countersink at openings
• Height: 14 in.
• Made from 7-gauge steel
• Galvanized (G90) for extra corrosion resistance
