DeckWise® HTSS™ Heat-Treated Deck Screws - #8 x 2" - 100 ct
DeckWise® HTSS™ (Heat-Treated Stainless Steel) deck screws represent the ultimate strength solution for fastening dense exotic hardwoods. The heat-treatment process increases hardness and torque resistance for demanding installations. A four-sided nail point provides quick penetration, while serrated threads push material aside for reduced friction and splitting. Superior hold-down control keeps boards locked tight without backing out—a common problem with nails. Self-drilling design eliminates pre-drilling on most materials. 100-count package.

About this product
DeckWise® HTSS™ screws are engineered specifically for high-density tropical hardwoods, utilizing heat-treated 410-grade stainless steel to provide extreme torque resistance. These fasteners solve the common issue of screw heads snapping or shearing off when driven into dense materials like Ipe or Cumaru. They are designed for professionals who require the driving strength of carbon steel combined with the corrosion resistance of stainless steel.

- 4Constructing heavy-duty tropical hardwood boardwalks that require fasteners with high shear strength.
Pro tips for dense hardwoods
- Always pre-drill a pilot hole and a countersink hole when working with Ipe or Cumaru to ensure the screw head sits perfectly flush and to prevent wood splitting.
- Use a standard drill with an adjustable clutch rather than a high-impact driver to maintain control and prevent over-torquing the 410-grade steel.
- In environments within 5 miles of saltwater, 316-grade stainless steel is recommended over 410-grade to provide maximum protection against chloride corrosion.
- Apply a small amount of wax or lubricant to the screw threads to further reduce friction when driving into the densest tropical species.

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.
