Simpson Strong-Drive SDWS Framing Screw with Quik Guard Coating, 0.160" diameter x 2-1/2" length is engineered and load-rated as a direct structural replacement for 16d, 10d, and 8d nails in wood framing applications. Built by Simpson, this framing fastener delivers superior holding power and pull-out resistance compared to common nails, making it a reliable choice for contractors and builders who need code-compliant performance in structural wood assemblies. Listed under IAPMO UES ER-192 and meeting both 2018 and 2021 IRC and IBC code requirements, this screw is purpose-built for demanding framing work where strength and compliance are non-negotiable.

Key Features

• Quik Guard Coating (Tan finish) - provides corrosion protection suited for framing environments, with a tan color that blends with wood surfaces for a clean appearance
• 0.160" shank diameter - sized to match the structural load ratings of 16d, 10d, and 8d nails, allowing direct nail replacement without over-engineering or under-building
• SawTooth Type-17 point - cuts into wood fibers aggressively for fast starts and reduced installation torque, eliminating the need for predrilling and speeding up framing work
• T25 6-Lobe drive recess - grips the bit tightly during driving for secure torque transfer and reduced cam-out, giving the installer better control and fewer drive failures
• Low profile head (0.450" diameter) - countersinks smoothly and sits flush with the wood surface, delivering a clean finish without raised fastener heads that can interfere with subsequent materials
• Serrated threads with 8-1/2 TPI, 1-1/8" thread length - serrations resist stripping and back-out, locking the fastener securely in place and maximizing pull-out resistance over the life of the structure
• Code listed under IAPMO UES ER-192 - meets 2018 and 2021 IRC and IBC requirements for common wood framing applications, so inspectors and engineers can confirm compliance without additional documentation

Why This Product

• Designed as a load-rated nail replacement for 16d, 10d, and 8d framing nails - installers can switch from nails to screws in structural framing without sacrificing code compliance or structural performance
• Superior pull-out resistance compared to nails means connections hold tighter over time, reducing the risk of joint failure in wood-framed structures subject to lateral or withdrawal forces
• The SawTooth Type-17 point eliminates predrilling on standard framing lumber, saving significant time and labor on large framing jobs where thousands of fasteners are driven
• Dual code compliance with both 2018 and 2021 IRC and IBC editions covers a wide range of jurisdictions and project timelines, reducing the need to source different fasteners for different inspection requirements

Frequently Asked Questions

What nail sizes does this screw replace in framing applications?

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

Do I need to predrill holes before driving this screw?

No predrilling is required. The SawTooth Type-17 point is designed to cut into wood fibers quickly, enabling fast installation with reduced torque so the screw can be driven directly into framing lumber without a pilot hole.

What building codes does this screw comply with?

The SDWS Framing screw is code listed under IAPMO UES ER-192 and meets 2018 and 2021 IRC and IBC code requirements for several common wood framing applications, making it suitable for use on projects subject to either edition of these codes.

What driver bit is needed to install this screw?

This screw requires a T25 6-Lobe (Torx-style) bit. The 6-lobe recess is designed to grip the bit tightly, providing secure drive control and reducing the risk of cam-out during installation.
