Simpson Deck-Drive DWP Wood Screw in Type 305 Stainless Steel by Simpson is engineered for deck, dock, boardwalk, and general exterior wood fastening applications where reliable corrosion resistance is essential. The #7 x 1-5/8" trim head screw features a sharp point and unique box-thread design that work together to deliver fast, clean penetration into today's most common decking and trim materials - giving installers a dependable stainless fastener that holds strong through wet, outdoor, and exposed conditions.

Key Features

• Type 305 Stainless Steel material - provides superior corrosion protection for exterior wood applications including decks, docks, fascia, and trim exposed to moisture and the elements
• Unique box-thread design with raised-ridge technology - greatly reduces driving torque so you can drive more screws per battery charge, improving efficiency on large projects
• Specially designed sharp point - penetrates hardwood and engineered wood products with ease, reducing the need for pre-drilling and speeding up installation
• T15 6-Lobe drive - provides a secure, slip-resistant bit fit that makes driving easier and extends bit life, reducing tool wear and downtime
• Trim head style with 0.230" head diameter - sits low and unobtrusive on the surface, making it ideal for fascia, millwork, and visible trim applications where a clean finish matters
• Compatible with wood, engineered wood, and polymer materials - offers versatile performance across the wide range of materials used in modern deck and exterior construction

Why This Product

• For projects where corrosion resistance is non-negotiable - docks, boardwalks, and outdoor decks exposed to rain and humidity - the Type 305 Stainless Steel construction offers long-term durability without the rust and staining concerns associated with standard steel fasteners
• The box-thread geometry is specifically designed for today's popular deck board profiles, meaning the screw seats properly and holds firmly in both solid lumber and engineered wood without excessive torque or splitting
• The trim head format keeps the fastener low-profile on the surface, making this screw an ideal choice for fascia boards, exterior millwork, and finishing applications where aesthetics and a clean look are priorities
• The sharp point and reduced-torque thread design work together to minimize installer fatigue and preserve battery power on cordless tools - a practical advantage on high-volume decking and dock projects

Frequently Asked Questions

What types of material can the Deck-Drive DWP Wood SS screw be used with?

The DWP Wood SS screw is designed for use with wood, engineered wood, and polymer materials - making it a versatile choice for most modern deck boards, fascia, and exterior trim applications.

Why does the box-thread design matter for deck installations?

The unique box-thread design with raised-ridge technology is specifically engineered to reduce driving torque compared to standard thread profiles. This means you drive more screws per battery charge on cordless tools, which adds up to real time and labor savings on larger decking and dock projects.

Is Type 305 Stainless Steel appropriate for coastal or seaside environments?

Type 305 Stainless Steel provides strong corrosion resistance for most exterior deck, dock, and general outdoor applications. For seaside and coastal environments with higher salt exposure, a Type 316 stainless steel option is recommended for maximum protection.

Why use a trim head screw for deck and fascia work?

The trim head design features a smaller 0.230 in. head diameter that sits low and discreet on the surface. This makes the DWP Wood SS screw particularly well suited for fascia boards, exterior millwork, and visible trim where a clean, low-profile finish is desired alongside secure fastening.
