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 305 or 316 stainless steel. 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.
