Simpson #9 x 1-1/2" Type 316 Stainless Steel SD Connector Screw by Simpson Strong-Tie is engineered specifically to replace nails in compatible Simpson Strong-Tie stainless-steel connectors, delivering superior load performance and long-lasting corrosion resistance in severe-exposure environments. With a 1/4 in. hex head drive and sharp point tip, this connector screw installs quickly and precisely - making it a reliable choice for structural fastening applications where hammer access is limited or where more installation control is needed. The Type 316 stainless steel construction makes it well-suited for coastal, marine, and other demanding outdoor environments where ordinary fasteners would fail prematurely.

Key Features

• Specifically designed to replace nails in certain Simpson Strong-Tie stainless-steel connectors - the only screw approved for that application, ensuring code-compliant and load-rated installations
• Single-fastener load values exceed those of typical 10d common nails - meaning fewer fasteners can achieve the same or greater holding strength in connector applications
• Type 316 stainless steel material - provides excellent corrosion resistance appropriate for severe-exposure environments including saltwater, chemical exposure, and harsh outdoor conditions
• 1/4 in. hex head drive with 0.370 in. head diameter - delivers positive driver engagement, reduces cam-out, and speeds up installation with a standard hex driver
• Sharp point tip - enables clean, self-starting penetration into connector holes without pre-drilling
• 1-1/4 in. thread length on a 1-1/2 in. overall length - maximizes thread engagement in structural members for secure, stable fastening
• 0.130 in. shank diameter - sized precisely for compatibility with Simpson Strong-Tie connector hole patterns, maintaining structural integrity at each fastening point
• Hex driver included - allows immediate use right out of the pack without needing additional tools for installation

Why This Product

• When a hammer is impractical - such as in tight framing bays or overhead connector installations - this screw delivers the same structural performance as nails while giving installers greater control and convenience
• For projects in coastal, marine, or high-moisture environments, Type 316 stainless steel offers superior resistance to corrosion compared to standard galvanized or zinc-plated fasteners, protecting the structural connection over the long term
• Because this screw is load-rated and tested for specific Simpson Strong-Tie connectors, it removes guesswork from the fastening selection process and supports inspection-ready, code-conscious builds
• Exceeding the load capacity of a 10d common nail means structural connectors can perform at full rated values without requiring additional or oversized fasteners - simplifying the installation process while meeting engineering requirements

Frequently Asked Questions

Can this screw be used as a direct nail replacement in any Simpson Strong-Tie connector?

This screw is specifically designed to replace nails in certain Simpson Strong-Tie stainless-steel connectors - not all connectors. It has been tested and approved for use in many popular Simpson Strong-Tie products. Always verify the connector's installation requirements to confirm this screw is approved for your specific application.

How does the load capacity of this screw compare to a common nail?

The single-fastener load values achieved by this SD Connector screw exceed those of typical 10d common nails, making it a strong-performing alternative in approved connector applications.

Why is Type 316 stainless steel significant for this connector screw?

Type 316 stainless steel provides excellent corrosion resistance appropriate for severe-exposure environments - including coastal, marine, and high-moisture outdoor settings - where standard or lightly coated fasteners may corrode and compromise structural connections over time.

What tool is needed to drive this screw, and is it included?

This screw uses a 1/4 in. hex drive. A hex driver is included with your purchase, so you can begin installation without sourcing additional tooling separately.
