About this product
DeckWise® #8x1-3/4" Heat-Treated Deck Screws are high-performance 305-grade stainless steel fasteners specifically engineered for the extreme density of tropical hardwoods. These screws undergo a specialized heat-treating process to increase torque strength, preventing the common issue of screw heads snapping during installation in woods like Ipe and Cumaru. They are designed for contractors and homeowners who require a durable, color-matched face-fastening solution for 3/4-inch thick exotic decking and siding.

Pro tips for dense hardwoods
- Pre-drilling is mandatory: Even with a Type 17 point, always use a 1/8" drill bit or a specialized countersink tool to prevent snapping the screw or splitting the dense wood fibers.
- Drive speed control: Use a drill with a clutch setting and lower RPMs when finishing the drive to avoid over-driving the head into the board.
- Coastal consideration: For projects located within one mile of saltwater, 316-grade stainless steel is recommended over 305-grade for maximum longevity.
- Bit replacement: Replace T15 driver bits at the first sign of wear to ensure a tight fit and prevent damaging the color-matched coating on the screw heads.

Why Choose Screws & Fasteners?
How to Face-Screw Hardwood Decking
Pre-Drill Every Hole
Dense hardwoods (1,500+ Janka) will split without a pilot hole. Use a countersink bit sized for your screw shank — this is non-negotiable for Ipe, Cumaru, and similar species.
Choose Stainless Steel
Carbon steel screws corrode and stain hardwood within months. Always use Type 316 stainless steel — it offers the best corrosion resistance for exotic hardwoods and coastal environments. The slight premium pays for itself in zero staining and no fastener failures.
Drive to Depth — Not Beyond
Set screws flush with the surface or just barely countersunk. Over-driving creates water-collecting craters that accelerate checking around each hole.
Two Screws Per Joist Crossing
Place one screw roughly 1″ from each board edge at every joist. This prevents cupping and ensures the board stays flat over time.
Pro Tip from Our Deck Specialists
Apply a drop of wax or soap to each screw tip before driving — it dramatically reduces friction and prevents snapped screw heads in ultra-dense wood like Ipe.
