Specifications
Simpson Strong-Tie SDS Heavy-Duty Connector Screws made from 316 stainless steel deliver unmatched strength and corrosion resistance for demanding structural and outdoor applications. These structural fasteners are specifically engineered to replace traditional through-bolts and lag screws in wood connections, providing high-load performance with easier, faster installation.
Built to perform in the harshest environments - including marine, coastal, and chemically treated wood—these screws resist rust, pitting, and staining over time. The proprietary thread design ensures maximum holding power while reducing installation torque.
Key Features:
- 316 Stainless Steel Construction – Maximum corrosion resistance for marine, coastal, and chemically treated wood environments.
- Heavy-Duty Performance – Replaces lag screws and through-bolts in structural wood connections.
- High Load Capacity – Designed and tested for load-rated connections in Simpson Strong-Tie connector applications.
- Patented Thread Profile – Engineered for high withdrawal resistance and reduced driving torque.
- No Pre-Drilling Required – Quick, efficient installation into wood without pre-drilling in most applications.
- Available Options – Choose from a variety of lengths and head styles (hex, 6-lobe, flat head) to suit your application and tools.
Applications:
- Ledger attachments
- Beam-to-post connections
- Deck construction in coastal or salt-exposed areas
- Pergolas, docks, and boardwalks
- Corrosive industrial or agricultural environments
- Any exterior or exposed wood application needing stainless strength
Installation:
- Select the correct length and head style for your connector and application.
- Compatible with most impact drivers and drills—no pre-drilling needed in typical wood applications.
- Follow all Simpson Strong-Tie connector installation guidelines for spacing and embedment.
- Use with Simpson connectors where SDS screws are specified for a code-compliant connection.
- Avoid mixing stainless with carbon steel fasteners to maintain corrosion resistance.
