Simpson Strong-Drive SDWS Framing Screw - 0.160" x 3-1/2" with Quik Guard Tan Coating is a high-performance structural fastener engineered to replace common framing nails - including 16d, 10d, and 8d nails - in wood framing applications. Featuring a SawTooth Type-17 point, serrated threads, and a low-profile head, this screw drives fast, countersinks cleanly, and delivers superior holding power and pull-out resistance compared to traditional nails. The Quik Guard tan coating provides added protection, making these screws a reliable choice for professional framing contractors and structural builders who need code-compliant fasteners they can depend on.

Key Features

• 0.160" Shank Diameter - engineered to match the load ratings of 16d, 10d, and 8d nails, providing a direct, code-recognized nail replacement in structural framing
• 3-1/2" Length with 2" Thread Length - delivers deep thread engagement into framing members for strong, secure connections in dimensional lumber assemblies
• SawTooth Type-17 Point - cuts through wood fibers quickly for fast installation with reduced torque, eliminating the need for predrilling
• Serrated Threads at 8-1/2 TPI - grip wood fibers aggressively to maximize withdrawal resistance and pull-out strength over the life of the connection
• Low Profile Head (0.450" diameter) - countersinks easily for a clean, flush finish without damaging surrounding wood surface
• T25 6-Lobe Drive - creates a tight bit-to-recess fit for more controlled driving, reduced cam-out, and faster, more secure installation
• Quik Guard Tan Coating - provides corrosion protection suited for use in wood framing environments where fastener durability matters
• Code Listed under IAPMO UES ER-192 - meets 2018 and 2021 IRC and IBC requirements for common wood framing applications, giving builders confidence in compliance

Why This Product

• Designed as a direct load-rated replacement for 16d, 10d, and 8d framing nails - so you can use screws in applications where nail schedules are specified without compromising structural integrity or code compliance
• Superior holding power and pull-out resistance compared to nails means framing connections stay tight under load, reducing callbacks and improving long-term structural performance
• The SawTooth Type-17 point and T25 6-Lobe drive work together to speed up installation - no predrilling required, less torque needed, and less driver bit slippage during high-volume framing work
• Listed under IAPMO UES ER-192 and compliant with 2018 and 2021 IRC and IBC codes, this screw meets inspector requirements for several common wood framing applications without additional engineering documentation

Frequently Asked Questions

Can the SDWS Framing Screw replace nails in code-required framing connections?

Yes. The SDWS Framing screw is designed and load-rated specifically to replace 16d, 10d, and 8d nails in framing applications. It is code listed under IAPMO UES ER-192 and meets 2018 and 2021 IRC and IBC requirements for several common wood framing applications.

Do I need to predrill for this screw?

No predrilling is required. The SawTooth Type-17 point cuts into wood fibers quickly, enabling fast installation with reduced torque so you can drive directly into framing lumber without a pilot hole.

What drive bit does this screw require?

This screw uses a T25 6-Lobe drive. The 6-lobe recess provides a tight, secure fit with a T25 bit for better drive control and reduced cam-out during installation.

Is this screw stronger than a comparable framing nail?

According to Simpson, the SDWS Framing screw is superior to nails in both holding power and pull-out resistance, making it a structurally stronger fastener choice for wood framing connections where withdrawal loads are a concern.
