Deck Screws & Fasteners
Corrosion-resistant screws engineered for hardwood, composite, and pressure-treated decking
Corrosion Resistant
Type 305/316 stainless steel withstands moisture and salt air
Self-Drilling
Hardened tips penetrate dense hardwoods without pre-drilling
Low Profile
Trim-head designs sit nearly flush with the wood surface
Our deck screws feature premium stainless steel construction, self-drilling tips, and specialized head designs for different decking materials. Choose trim-head for minimal visibility or bugle-head for maximum holding power.

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.

Deck Screw Types Compared
Head style controls how visible the fastener is and how much holding power you get. Material grade controls how long it survives your climate.
| Option | Profile | Best for | Trade-off |
|---|---|---|---|
| Trim-head, Type 305 stainless | Small head, sits nearly flush | Inland hardwood decks where you want minimal fastener visibility | Less bearing surface than a bugle head |
| Bugle-head, Type 305 stainless | Wider self-countersinking head | Maximum holding power on face-screwed decking | More visible on the finished surface |
| Trim-head, Type 316 stainless | Small head, marine-grade alloy | Coastal, poolside, and dock exposure | Higher cost per fastener |
| Countersink screw for plugging | Driven below surface into a bored recess | Decks that will be plugged for a fastener-free look | Requires a countersink bit and a plugging step |
| Composite deck screw | Painted head, reverse thread under head | Composite and capped boards | Not intended for dense tropical hardwood |

Installation Considerations
Dense tropical hardwood behaves nothing like treated pine when you drive a screw into it. Most fastener failures trace back to skipping one of these steps.
Predrill above roughly 1,500 Janka
Ipe, Cumaru, and Massaranduba are dense enough to split at board ends and to snap fasteners. Predrill the full depth of the screw, not just the top of the board.
Two screws per board per joist
Standard practice on face-screwed decking is two fasteners at each joist crossing, held in from the board edge far enough to avoid splitting out.
Match alloy to exposure
Type 305 stainless is the usual choice for inland decks. Type 316 resists chloride attack and is the correct specification for salt air, pool chemicals, and marine work.
Keep fasteners back from board ends
End grain splits far more readily than the field of the board. Hold fasteners in from the ends and predrill those locations without exception.
Control driving depth
Overdriving crushes wood fibers around the head and creates a water trap. Drive to flush, or to a consistent depth if you are plugging.
Common Mistakes
Skipping predrilling on dense hardwood
Do this instead: Predrill every fastener location. It is faster overall than backing out snapped screws and replacing split boards.
Using coated or galvanized screws near salt water
Do this instead: Specify Type 316 stainless for coastal, dock, and pool decks where chloride exposure is constant.
Using composite deck screws in tropical hardwood
Do this instead: Choose a hardwood-rated stainless screw; composite screws are designed for a much softer material.
Driving screws too deep
Do this instead: Set the driver clutch and drive to flush so water is not held against a crushed fiber pocket.
