Key Features
316 Stainless Build Type 316 stainless steel gives this screw the corrosion resistance needed for exterior connector work and harsh environments where standard fasteners are the weak link. Nail Replacement The Simpson Strong-Tie SD9112SS-R500 Strong-Drive SD Connector SS Screw is designed to replace nails in approved Simpson Strong-Tie stainless-steel connectors, giving you better installation control with a drill. Hex Head Control The 1/4 inch hex head with integrated washer seats cleanly in connector holes and makes the fastener easy to drive, identify, and check after installation.
Overview
The Simpson Strong-Tie SD9112SS-R500 Strong-Drive SD Connector SS Screw is a #9 x 1-1/2 inch stainless steel connector screw built for fastening approved Simpson Strong-Tie stainless-steel connectors in wood framing. This is a connector screw designed for replacing nails in structural connector applications. Model Number: SD9112SS-R500. If you want the installation control of a screw without giving up load-rated connector performance, this is the fastener this product line was made around.
What matters here is not just that it is a screw, but that it is engineered for a very specific job. Simpson states this is the only screw approved for certain stainless-steel connector applications, and the single-fastener load capacity of the #9 SD SS exceeds the capacity of a 10d common nail. That matters when you are working with approved hangers, ties, and connector hardware and need a fastener that matches the connector design instead of improvising with a general-purpose wood screw.
The dimensions are set up for connector work, not generic decking or trim work. This screw uses a #9 shank, a 1-1/2 inch overall length, a 0.130 inch shank diameter, and a 1-1/4 inch thread length. The shank is specifically designed to match the fastener holes in Simpson Strong-Tie connectors, which helps the screw fit and seat the way the connector manufacturer intended. The 0.370 inch integrated washer under the hex head spreads the bearing surface and helps the head sit properly against the connector.
Installation is where this style of fastener really earns its keep. In tight framing bays, overhead work, retrofit situations, and spots where swinging a hammer is awkward, a drill or impact driver is simply more controlled. The 1/4 inch hex head gives solid driver engagement, and Simpson includes a hex driver in the package. That means less slipping at the head and easier starts when you are working one-handed or reaching into a cramped connector location.
Material choice is another big reason to buy this exact screw instead of a look-alike. The SD9112SS-R500 uses Type 316 stainless steel, which is the right conversation for corrosion resistance in exterior applications and more aggressive environments. When you are pairing stainless-steel connectors with stainless fasteners, you are building the connection as a system instead of mixing materials and hoping for the best.
This 500-count pack makes sense for pros who are stocking for repeated connector installs, deck framing near coastal exposure, exterior structural repairs, or larger framing jobs where approved stainless hardware is required. It is a strong fit for contractors, framers, deck builders, remodelers, and serious DIY users who already know that connector fasteners are not the place to substitute whatever is in the bucket.
Built for Approved Connector Installs
This screw is made for connector fastening, not guesswork. If the job calls for approved fasteners in a Simpson Strong-Tie stainless-steel connector, using the right screw saves time and keeps the connection aligned with the application it was tested for.
- Designed to replace nails in certain Simpson Strong-Tie stainless-steel connectors
- Single-fastener load capacity of the #9 SD SS exceeds a 10d common nail
More Control in Tight and Overhead Work
Connector work often happens where a hammer is inconvenient. A hex-head connector screw lets you drive fasteners with better control, especially when you are working inside corners, between members, or above shoulder height.
- 1/4 inch hex drive engages securely with common drivers
- Hex driver is included for immediate installation
Easy to Identify After Installation
The head design is more than cosmetic. The integrated washer gives the head a wider bearing surface, and the stamped markings make it easier to identify the installed fastener when you are checking a connection later.
- 0.370 inch head diameter with integrated washer
- Head is stamped for easier post-install identification

Pro Tip
Keep these separated from your general wood screw stock and use them only where the connector schedule calls for approved SD Connector SS screws. On connector jobs, the fastener is part of the engineered connection, not just something that fits the hole.
