Ideal for use with treated lumber, hardwoods, chipboard, and other tough materials, these screws are a must-have for professionals seeking reliable, long-lasting fastening solutions.

Standout Features of Big Timber STX™ Screws

• Grade 305 Stainless Steel for Superior Durability
  Constructed from high-quality stainless steel, these screws are engineered to resist corrosion for up to 1200 hours in both ACQ and salt spray conditions, ensuring long-term reliability.
• Self-Countersinking True Flat Head with Cutting Nibs
  The flat head design with under-head cutting nibs allows for a flush, professional finish, while reducing surface damage and making installation smoother.
• T-25 Star Drive for Optimal Torque
  The star drive design handles twice the torque of traditional Phillips or square drives, reducing cam-out and extending the life of the bit. This design ensures a secure installation with minimal effort.

Engineered for Superior Performance

• Deep, Wide Threads and Knurled Shank
  The deep-cutting threads provide maximum holding power, and the knurled shank reams the hole to reduce drag and prevent splitting, making driving the screw easier and less tiring.
• Spiral Notches and Type 17 Point
  Spiral notches cut through fibrous materials, reducing the torque needed for installation without compromising holding power. The Type 17 notched point starts quickly without “walking” and eliminates the need for pre-drilling.

Perfect for Harsh and Coastal Environments
Designed to perform in challenging conditions, Big Timber STX™ screws are ideal for projects in coastal areas, pool decks, livestock confinement structures, deck framing, fencing, and laminated beams. Whether used in residential or commercial projects, these screws deliver reliable performance that professionals trust.
