The Simpson #6 x 1-7/8 Collated DWHL Drywall Screw is a high-performance fastener from Simpson engineered specifically for drywall to wood framing attachment. Built around a hi-lo thread design and sharp point, this screw delivers reliable penetration and secure holding power across standard interior wall and ceiling installations. Curved collation keeps screws feeding smoothly and consistently through compatible auto-feed systems, making these an efficient choice for high-volume drywall work.

Key Features

• Bugle head design - countersinks cleanly into drywall face paper without tearing the surface, leaving a flush, damage-free finish ready for taping and finishing
• #2 Phillips drive - provides positive bit engagement to reduce cam-out during high-speed driving, keeping installation fast and accurate
• High-low thread pattern - alternating thread heights improve pull-out resistance in wood substrates while reducing the driving torque required, so crews work faster with less fatigue
• Sharp point - starts immediately on contact with drywall and wood framing, eliminating the need for pre-drilling and speeding up the installation process
• Gray phosphate coating - reduces friction during driving and provides corrosion resistance suited to standard interior applications
• Curved collation strip - ensures smooth, consistent screw feeding in compatible auto-feed tools, including the Quik Drive PRO200G2 and PRO250DWG2, minimizing jams and downtime on the job

Why This Product

• Purpose-built for drywall to wood installation - every design element, from the hi-lo threads to the sharp point and bugle head, is optimized for attaching drywall panels to wood studs and framing, so the screw performs exactly as needed without workarounds
• Engineered for auto-feed compatibility - curved collation is matched to the Quik Drive PRO200G2 and PRO250DWG2 systems, giving contractors a seamless, consistent feed cycle that keeps high-volume projects moving
• Reduced driving effort without sacrificing grip - the hi-lo thread geometry lowers required torque during installation while maintaining strong pull-out resistance in wood framing, striking a practical balance between speed and holding power
• Driver bit included - each box ships with a #2 Phillips driver bit, so work can start immediately without a separate accessory purchase, and replacement bit model BIT2P is available when needed

Frequently Asked Questions

What type of application are DWHL178PS screws designed for?

These screws are specifically designed for drywall to wood applications, making them ideal for attaching drywall panels to wood studs and framing during interior construction and renovation projects.

Which auto-feed screw tools are compatible with these collated drywall screws?

The DWHL178PS is compatible with the Quik Drive PRO200G2 and PRO250DWG2 auto-feed screw systems, which work in conjunction with the curved collation strip to deliver fast, consistent fastening.

What is the advantage of high-low threads on a drywall screw?

High-low threads feature alternating thread heights that improve pull-out resistance and holding strength in wood substrates while also reducing the driving torque required, allowing for faster and easier installation.

How many screws come in a box of DWHL178PS?

Each box contains 2,000 collated drywall screws along with a driver bit, making it well-suited for large-scale drywall installation projects where volume and efficiency are priorities.
