The Simpson Strong-Tie HDQ Holdown is a high-capacity structural holdown designed to anchor wood shearwalls and posts to concrete foundations. It transfers uplift and overturning forces from wood framing into the foundation, helping protect structures in high-wind and seismic conditions.

Built for high uplift resistance, the HDQ series delivers strong lateral load support in a more compact profile than traditional holdowns. The pre-installed SDS structural screws simplify installation while providing a secure, code-compliant connection to wood studs or posts.

Featuring a compact heavy design, this structural connector provides maximum load performance without increasing wall width. Available in multiple finish options, the HDQ holdown can be selected based on required load capacity and environmental exposure.

Key Features:

• High Load Capacity: Designed to resist significant uplift and overturning forces.
• SDS Screws Included: Pre-engineered structural screws provide fast, reliable installation.
• Compact Profile: Delivers heavy-duty performance in a space-saving design.
• Pre-Engineered System: Tested holdown connector for shearwall applications.
• 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.
