The Simpson Strong-Tie HDB Bolted Holdown is a structural holdown anchor designed to secure wood shearwalls and posts to concrete foundations. It transfers uplift and tension forces from wood framing into the foundation, helping stabilize structures during wind and seismic events.

Engineered for high uplift resistance, the HDB series delivers dependable performance in demanding shearwall applications. Its bolted attachment design creates a strong, reliable connection to wood studs, posts, or built-up columns where enhanced lateral load resistance is required.

Designed with a pre-deflected body, this structural connector helps reduce deflection under tension for tighter performance. Available in multiple finish options, the HDB holdown can be selected based on environmental exposure and corrosion requirements.

Key Features:

• High Uplift Resistance: Transfers tension forces from wood framing into concrete foundations.
• Bolted Connection: Secures to studs, posts, or columns using a field-proven bolt installation method.
• Pre-Deflected Design: Minimizes deflection under load for improved structural performance.
• Multiple Finish Options:
  • Hot Dip Galvanized: ideal for exterior, high-moisture, or treated lumber applications requiring enhanced corrosion protection.
  • G90 Galvanized: best suited for interior, dry environments with minimal exposure to moisture.
