TOPLoc Stainless Steel 3" Deck Screws for TimberTech Decking
What TOPLoc Stainless Steel 3″ Deck Screws Are
- TOPLoc 3″ Stainless Steel Deck Screws for TimberTech and TOPLoc 3″ #305 Stainless Steel Composite Fasteners are high-quality #305 stainless steel screws made for securely fastening TimberTech deck boards (especially PRO and EDGE composite boards) from the top-down.
- TOPLoc Color‑Matched 3″ Deck Fasteners adds color-matched heads so the fasteners blend with TimberTech board finishes (like Teak, Cedar, Gray, etc.), helping the screws look neater.
- Typically you get a box sized for ~85 sq ft of decking when it’s the 3″ version — enough for many field boards when spacing is standard.
Why Stainless Steel Matters
- Corrosion resistance: Marine-grade or #305 stainless steel resists rust better than coated steel, especially around moisture and near coastal environments. That’s important for PVC/composite decking like TimberTech.
- Durability: Stainless fasteners maintain strength and appearance over many years.
How These Are Used
- Face fastening: These screws go through the board face into the joist — ideal when you can’t use a hidden clip system (for example, with square-shoulder boards or at perimeter boards and stairs).
- Top-down installation: Make sure to use the TORX® ttap® bit included or specified — it gives solid drive engagement in dense composite material.
- No pre-drilling usually required: With TimberTech’s recommended fasteners like TOPLoc, pre-drilling isn’t often needed, but check the specific board and screw recommendations in the installation guide.
About this product...
TimberTech's TOPLoc Stainless Steel Face Fastening System delivers a color-matched fastener option ideal for dense boards or situations where hidden fasteners are not preferred. TOPLoc screws are compatible with all TimberTech decking. TOPLoc screws are compatible with TimberTech XLM, Earth wood Evolutions, Twin Finish, DockSider planks and Relia Board decking. Face fastening screws take the guesswork out of which screw looks best or installs easiest, delivering a color-matched fastener option that’s ideal for dense boards or situations where hidden fasteners cannot be used. TOPLoc™ screws are specifically designed for our deck boards – they eliminate the ‘mushrooming’ effect that standard decking screws cause when used with composite wood materials.
