The Strong-Drive DWP Wood SS screw is a beast! Sized at a solid #14 and available in lengths from 3" to 6", this powerful, load-rated fastening is your solution for deck, dock and general exterior applications where extra corrosion protection and load specifications are required. The #14 Strong-Drive DWP Wood SS flat-head screws are structural fasteners that have been tested in accordance with ICC-ES acceptance criteria AC233 and are load rated for shear, pull-through and withdrawal resistance. With its specially designed sharp-point and unique box-threads, the DWP WOOD SS is a great solution for exterior engineered structural connections. Manufactured from Type 316 stainless steel, it's the ultimate solution for coastal and extreme corrosion environments.  

  • Unique squared-off “box” thread design with raised-ridge crest technology greatly reduces driving torque, allowing you to drive more screws on a single battery charge.
  • Specially designed sharp point easily penetrates hardwoods.
  • Suitable for use with wood, engineered wood and polymer materials
  • 6-lobe drive (also known as Torx or Star drive) provides a snug interface resulting in an easy drive and long bit life.

  • Decking, Docks, Boardwalks and Piers; all structural application in coastal environments.  

  • 6-lobe bit included: BIT27T-2-R2

Grades of Stainless Steel

304/305 Grades
Thesw two grades share 98% of the elements making up their alloy composition, with 305 having slightly more carbon. A very popular choice with excellent corrosion resistance and good qualities of strength. Slightly cheaper than 316 Grade, it is a durable and aesthetically pleasing choice for all construction applications.

316 Grade
The addition of molybdenum to the mix is what sets this Marine Grade Stainless Steel apart. Used in highly corrosive environments, this grade is the ultimate choice for structures built close to or even within the ocean or bodies of water. There is no better material for fasteners designed for coastal applications, including docks, jetties, decks, fences and roofs.

When to Use Which Grade?

304/305 Grade

  • For general outdoor applications, such as decking and fencing.
  • In areas with moderate exposure to moisture and pollution.
  • For projects that require a medium to high level of corrosion resistance.
  • When cost is a consideration, as 304 grade is more economical than 316 grade.

316 Grade

  • For extreme outdoor applications in coastal areas and regions prone to heavy rainfall and high humidity.
  • In areas with high levels of chlorine, such as pool decks and hot tub structures.
  • In areas with direct exposure to salt water, such as marinas, floating docks, or boardwalks.
  • Able to withstand exposure to the high heat and humidity of saunas.
