The Simpson Strong-Tie HD Stainless Steel Bolted Holdown offers high-capacity tension anchoring with superior corrosion resistance. Engineered for exterior and corrosive environments, this stainless steel holdown is ideal for marine, coastal, and chemically sensitive installations where long-term durability and structural integrity are critical.

Available in multiple model sizes, the HD stainless series is designed for use in wood framing to anchor shearwalls, narrow walls, and structural tie-downs where code compliance and extreme environmental performance go hand-in-hand.

Key Features:

• 304 Stainless Steel Construction: Excellent corrosion resistance in coastal, marine, and chemical-exposure conditions.
• High-Strength Load Ratings: Engineered to resist uplift and lateral forces in tension tie systems.
• Bolted Design: Allows secure anchoring to framing and foundation using through-bolts or structural screws.
• Pre-Drilled Holes: Precise hole patterns for easy alignment with anchor bolts and framing hardware.
• ICC-ES Evaluated: Meets rigorous testing standards for tension applications under IBC and IRC codes.

Applications:

• Coastal and marine construction
• Shearwall anchorage in treated lumber
• Outdoor decks and covered structures
• Seismic holdown requirements in corrosive zones
• Multi-story framing in high-humidity or salt air regions

Installation Notes:

• Use with stainless steel or approved hot-dip galvanized anchor bolts for full corrosion protection.
• Fasten to framing members using Simpson SDS screws or bolts per model-specific specs.
• Follow all manufacturer spacing and edge distance guidelines for optimal load performance.
• Reference Simpson Strong-Tie ESR reports and load tables for compliant design integration.
