The Simpson Strong-Drive SDWS Framing Screw with Quik Guard Coating is a high-performance structural fastener engineered to replace 16d, 10d, and 8d nails in wood framing applications - delivering superior holding power and pull-out resistance compared to traditional nails. At 0.160 in. in diameter and 4 in. in length, this screw is load-rated for common structural framing tasks and is code listed under IAPMO UES ER-192, meeting both 2018 and 2021 IRC and IBC requirements. The tan Quik Guard coating provides corrosion resistance suited for treated lumber and outdoor framing environments, making this screw a reliable choice for contractors and builders who need code-compliant fasteners with performance they can count on.

Key Features

• SawTooth Type-17 Point - enables fast, self-starting installation with reduced torque, eliminating the need for predrilling and speeding up framing work.
• T25 6-Lobe Drive - provides a tight, secure fit between the bit and recess, giving installers better drive control and reducing cam-out during high-torque driving.
• Low Profile Head (0.450 in. diameter) - countersinks cleanly and easily into wood for a flush, smooth finish that won't interfere with surface materials or adjacent framing members.
• Serrated Threads with 8-1/2 TPI and 2-1/2 in. thread length - grip wood fibers aggressively for exceptional pull-out resistance and holding strength that outperforms standard nails.
• 0.160 in. shank diameter - load-rated specifically to replace 16d, 10d, and 8d nails, giving builders a structurally equivalent and code-compliant nail substitute.
• Quik Guard Coating in tan - resists corrosion and blends discreetly into framing lumber, helping protect fastener integrity in demanding construction environments.
• Code listed under IAPMO UES ER-192 - meets 2018 and 2021 IRC and IBC requirements, giving inspectors and contractors confidence in code compliance for structural framing applications.

Why This Product

• Designed as a load-rated nail replacement for 16d, 10d, and 8d nails - installers get a single fastener that covers multiple common framing nail sizes with verified structural performance.
• The SawTooth Type-17 point drives fast with reduced torque and no predrilling required - reducing labor time and tool wear on the job site without sacrificing structural integrity.
• Code listed under IAPMO UES ER-192 and compliant with both 2018 and 2021 IRC and IBC standards - this screw is built for projects where inspection and code compliance are non-negotiable.
• Superior pull-out resistance and holding power compared to nails - serrated threads and a robust 0.160 in. shank diameter mean connections stay tight under load, shear, and withdrawal forces.

Frequently Asked Questions

What nails does the SDWS Framing Screw replace?

The SDWS Framing screw is designed and load-rated to replace 16d, 10d, and 8d nails in wood framing applications, offering superior holding power and pull-out resistance compared to those traditional nail sizes.

What code standards does this framing screw meet?

This screw is code listed under IAPMO UES ER-192 and meets the requirements of the 2018 and 2021 IRC (International Residential Code) and IBC (International Building Code) for several common wood framing applications.

Do I need to predrill before driving this screw?

No predrilling is required. The SawTooth Type-17 point is specifically designed to start fast and drive with reduced torque, allowing for quick installation directly into wood framing members.

What bit is needed to drive the SDWS Framing Screw?

This screw uses a T25 6-Lobe (Torx-style) drive recess. A T25 driver bit is required, which provides a tight, secure connection to the recess for improved drive control and reduced slippage during installation.
