Product Description

The Simpson Deck-Drive DWP Wood SS Screw is a high-performance collated fastener engineered for deck, dock, and general exterior applications where extra corrosion protection is needed. Built from Type 316 stainless steel, it delivers superior resistance to salt air and moisture, making it a reliable choice for coastal and seaside installations. A specially designed sharp point drives through hard wood products with ease, while the unique box-thread design with raised-ridge technology dramatically reduces driving torque for faster, smoother, less fatiguing installation. Designed for use with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment, this curved-collated screw keeps high-volume deck board fastening moving at pace. Three T25 6-lobe driver bits are included to get the job started right away.

Key Features

  • Type 316 stainless steel construction - provides superior corrosion resistance for seaside, coastal, dock, and exterior environments where standard fasteners fall short.
  • Unique box-thread design with raised-ridge technology - greatly reduces driving torque, so installation is faster and less physically demanding over long runs of decking.
  • Specially designed sharp point - penetrates hard wood products with ease, eliminating the need for pre-drilling and keeping work moving without interruption.
  • T25 6-lobe drive - helps prevent driver-bit cam-out while driving easier and extending bit life, reducing frustration and replacement costs on large projects.
  • Flat head profile - sits flush with the deck surface for a clean, finished appearance on decks, docks, fascia, and trim applications.
  • Curved collation format - compatible with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed system, enabling rapid, consistent fastening across large deck and boardwalk surfaces.
  • Three T25 6-lobe driver bits included - lets crews get to work immediately, with a known replacement bit reference for ongoing jobs.

Why This Product

  • Purpose-built for demanding outdoor environments - Type 316 stainless steel is specifically suited for seaside and coastal applications where exposure to salt air, moisture, and the elements would quickly degrade standard fasteners.
  • Engineered to work with the wood decking used today - the combination of a sharp point and box-thread design with raised-ridge technology means these screws are ideally suited for the majority of wood deck boards, reducing splitting, cam-out, and installation fatigue.
  • Designed for high-volume, auto-feed installation - the curved-collated format pairs directly with the Simpson Strong-Tie Quik Drive PRO300SG2 system, making this screw a natural fit for contractors tackling large deck, dock, or boardwalk projects where speed and consistency matter.
  • Versatile across multiple exterior applications - equally at home fastening deck boards, dock framing, and fascia and trim, this screw reduces the number of different fasteners a crew needs to stock for exterior wood construction work.

Frequently Asked Questions

Why is Type 316 stainless steel recommended for this application?
Type 316 stainless steel offers superior corrosion resistance compared to standard stainless grades, making it specifically suited for seaside and coastal environments where exposure to salt air and moisture is a concern. These screws are designed for deck, dock, and general exterior applications where extra corrosion protection is needed.
What tool is required to install these collated screws?
These screws are designed to install with the Simpson Strong-Tie Quik Drive PRO300SG2 auto-feed screw driving system or attachment. The collated curved format is compatible with that system, making them well suited for high-volume deck board installations.
What drive type do these screws use, and are driver bits included?
These screws use a T25 6-lobe drive, which helps prevent driver-bit cam-out while driving easier and extending bit life. Each 1,000-count pack includes three T25 6-lobe driver bits. If replacement bits are needed, the compatible replacement bit is the BITTX25.
Do these screws require pre-drilling when installing into hardwood deck boards?
In most applications, pre-drilling is not necessary. The specially designed sharp point is engineered to penetrate hard wood products with ease, and the unique box-thread design with raised-ridge technology greatly reduces driving torque to make installation faster and less fatiguing.
