SPAX® 304 series stainless steel screws offer premium corrosion resistance and long-term aesthetics in wood deck/railing, fencing and other exterior wood applications.

T-STAR plus PowerDeck® Trim Head, Double ThreadLok™
These fasteners are engineered for wood deck board and railing baluster applications. Unique Double ThreadLok™ design pulls and holds boards tight, preventing screws from backing out and boards from squeaking as lumber dries out. T-STAR plus drive provides superior bit engagement over phillips and square drive screws.
