Sq. Drive 304 Series Stainless Steel Screws with Double Threadlok™.


SPAX® 304 Series Stainless Steel Screws offer premium corrosion resistance and long-term aesthetics in wood deck/railing, fencing and other exterior wood applications. Trim head design with a square drive system for flush finish applications.

  • Patented thread serrations require no pre-drilling and reduce driving torque to prolong the battery life of power tools
  • Ideal for use in cedar and redwood applications to prevent possible staining of the wood

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.
