The Strong-Drive DWP Wood Screw is just that - strong! This is a load-rated solution ideal for decking, docks, boardwalks and various exterior applications where high corrosion resistance and load-bearing capabilities are required. These flat-head screws are structural fasteners tested to meet ICC-ES acceptance criteria AC233, providing reliable shear, pull-through, and withdrawal resistance. The DWP Wood SS features a specially designed sharp point and distinctive box threads, reducing both driving torque requirements and likelihood of splitting the lumber. 

Key Features

  • The unique squared-off box thread design with raised-ridge crest technology minimizes driving torque, allowing more screws to be driven per battery charge.
  • The sharp point is engineered to easily penetrate hard wood products.
  • Suitable for use with wood, engineered wood, and polymer materials.
  • The 6-lobe drive (also known as Torx or Star drive) ensures a secure fit with the bit, facilitating easier driving and extending bit lifespan.
  • Also available in Type 316 stainless steel, recommended for coastal applications.

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.
