Simpson Strong‑tie Hdue13‑sds3.5 Galvanized 12‑gauge Pre‑deflected Wood‑frame Holdown – High‑capacity Sds Connector

Introducing the Simpson Strong‑Tie HDUE13‑SDS3.5 Pre‑Deflected Holdown, a high‑performance, 12‑gauge carbon‑steel connector finished in corrosion‑resistant galvanized coating. Engineered for today’s expansive residential wood structures, this holdown excels in three‑story homes, large window openings, and tight shear‑wall layouts, delivering superior overturning resistance where space is at a premium.

Why it matters: By anchoring shear walls, braced panels, and other lateral‑force members, this holdown safeguards your building against wind and seismic loads, extending the lifespan of the framing system while simplifying installation for contractors.

Designed with a patented pre‑deflection system, the holdown limits post‑bending and transfers forces directly into the foundation, reducing the risk of wall uplift. The overlapping back plate provides an enlarged bearing area that counters wood splitting, while the optimized screw layout ensures uniform load distribution across the post. Installation requires only a drill and the included Strong‑Drive® SDS screws, eliminating the need for separate lag bolts or nuts and accelerating on‑site work.

• Pre‑deflected seat geometry: Reduces movement under load, providing consistent performance and higher load ratings for residential framing.
• Overlapping back‑plate design: Increases shear capacity and distributes forces evenly across the wood post, minimizing split risk.
• Optimized Strong‑Drive® SDS screw pattern: Uses heavy‑duty connector screws that grip firmly, cut down on fastener slip, and preserve more of the post’s net cross‑section than traditional bolts.
• ICC‑ES AC155 certification: Meets rigorous testing standards, giving engineers and builders confidence in compliance and safety.
• Versatile sizing options: Available in a range of dimensions to meet diverse load requirements, allowing a one‑to‑one replacement for legacy HDU models without redesign.

Elevate your structural design: The HDUE13‑SDS3.5 combines shear and tension fasteners into a single, streamlined component, reducing the total number of screws while maintaining or exceeding the capacity of older connectors. Its galvanized steel construction resists rust in harsh environments, and the 12‑ga thickness ensures durability under repeated loading cycles. Whether you’re reinforcing a new custom home or retrofitting an existing build, this holdown delivers the confidence of a tested, code‑approved solution that integrates seamlessly with Strong‑Drive® SDS hardware. Choose the Simpson Strong‑Tie HDUE13‑SDS3.5 for a reliable, high‑capacity connection that protects your structure and speeds up the construction timeline.
