Self-Tapping Metal Joist Deck Screws

Stainless Steel Metal Joist Decking Screws

DeckWise Self Tapping Deck Screws

The DeckWise® Metal Joist deck screws are also available as an option with any Hidden Deck Fastener Kit in any combination.

For use with stainless steel, aluminum and steel deck framing systems.

More and more these days contractors, architects and DIY deck builders are utilizing metal joist sub-substructures to ensure longer-lasting, lower maintenance decks. The DeckWise® Self-Tapping Metal Joist Deck Screw is designed explicitly for metal joist applications.

This handy fastening screw can be used to attach most types of decking materials such as hardwoods, heat treated lumber (thermally modified), soft woods, composite and PVC with aluminum, stainless steel and steel substructures. Pre-drilling pilot holes through the decking is still recommended.

Our specially engineered auger tip will penetrate the metal joist underneath with ease. DeckWise® metal joist deck screws are high performance fasteners, which allow deck builders and architects to provide their customers with uniform and long-lasting clean surfaces when used with our Hidden Deck Fasteners.

Xlyan® Coating = Galvanic Corrosion Protection

Multiple purpose Xlyan® coating creates a barrier between different metals.

To answer the question of galvanic corrosion, yes, there is a reaction when two dissimilar metals are in contact with each other in the presence of an electrolyte (such as saltwater or moisture). This creates a reaction where the weaker of the two metals begins to corrode and sacrifices itself to the other metal. To protect against that, we use a Xlyan® coating. This coating is known for its excellent non-stick and low-friction properties, as well as its resistance to corrosion, chemicals, and high temperatures. Making the Xlyan® coating a multiple purpose coating for this application.

  • Low Friction: Xylan® coating reduces friction between the two surfaces, which improves the driving of the screws by acting as an added lubricant.
  • Temperature Resistance: Xylan® coatings can withstand high temperatures. Reduces the effects of heat on the screws during installation.
  • Corrosion Resistance: Xylan® Coatings offer protection against corrosion.

To further with the corrosion resistance; when galvanized steel and 410 stainless-steel with a Xylan® coating come into contact, the presence of the Xylan® coating can affect the galvanic reaction between the two metals. The Xylan® coating acts as a barrier between the galvanized steel and the 410 stainless-steel, reducing direct contact between the two metals and thus minimizing the potential for galvanic corrosion.

Other metal joist screw brands on the other hand are using a black epoxy style coating as a barrier to limit the potential for a galvanic reaction. But outside of it just being a tough coating, it does not offer the additional advantages that Xylan® does.
