DECKFAST® STAINLESS
PRODUCT NOTES
TREATED LUMBER DECKING
For use with all types of treated lumber decking. The flat head design of Deckfast Stainless is particularly suited to treated lumber decking, which can warp or cup to the extent that it can pull through smaller diameter screw heads.
CORROSION RESISTANCE
All exterior fasteners are subject to corrosion depending on installation and environmental factors. Where there are any particular concerns, Deckfast Stainless or Starborn's Headcote stainless steel screws with color coated heads should be used.

TREATED LUMBER DECKING
If you are using treated lumber decking, only flat head screws should be used as treated lumber can warp or cup to the extent that it can pull through a trim head screw.
PRE-DRILLING
For best results, Starborn's Smart-Bit pre-drilling and countersinking tool has been specifically designed to work together with Deckfast Stainless - as well as Starborn's Standard Headcote 305 (and 316) deck screws - to create the perfect hole and perfect fit every time.
Pre-drilling may be necessary in hardwoods. Deckfast Razorback can greatly reduce the need to pre-drill.
Some cellular PVC ("plastic") decking, such as AZEK Deck, will accept Deckfast Stainless - or Standard Headcote 305 (or 316) - without the need for pre-drilling. As a general rule, do not use composite screws in these all-plastic products. (Check with your deck board manufacturer's installation instructions for recommendations.)
As a general rule, using Deckfast Stainless in composite decking will require pre-drilling to avoid "mushrooming." For many composite deck board brands, use of Headcote Cap-Tor or Epoxy Coated Cap-Tor - will avoid the need to pre-drill.
Even where pre-drilling is not required, using Smart-Bit always guarantees the best results. The screw will be perfectly countersunk, with no mushrooming, raised edges, or rough edges.
Even decking material that doesn't require pre-drilling overall may still need pre-drilling at the ends of each board and where deck boards meet to avoid splitting.
