#8×1″ Bronze T-20 Flat Head Screws

Versatile, Durable, and Built to Last

Big Timber’s BTX™ #8×1″ Bronze Flat Head Screws are the go-to solution for exterior and interior construction projects that demand reliability and strength. Made from heat-treated, hardened steel and coated with a triple-layer bronze finish, these screws offer unmatched corrosion resistance and durability. Whether working with hard or soft woods, chipboard, or treated materials, these screws are engineered to drive smoothly and stay secure.

Why Choose Big Timber BTX™ Screws?

• Triple-Layer Corrosion Protection
  Coated for exterior use, these screws offer 1200 hours of protection against ACQ and salt spray conditions, ensuring long-term performance in harsh environments.
• Self-Countersinking True Flat Head
  The flat head with under-head cutting nibs provides a clean, flush finish and minimizes surface damage. The head is designed to countersink smoothly for professional results.
• Deep Star Drive Recess for Better Torque
  The T-20 star drive reduces cam-out and handles twice the torque of Phillips or square drives, prolonging bit life and making installation easier and more efficient.

Engineered for High Holding Power

• Aggressive Knurling and Spiral Notches
  The screw’s knurled shank reams the hole, reducing drag on the tool and splitting in the wood. Spiral notches in the threads allow the screw to cut through fibrous materials, reducing the torque needed without sacrificing holding power.
• Type 17 Notched Point
  The Type 17 tip starts quickly and precisely, eliminating the need for pre-drilling and preventing the screw from “walking” during installation.

Applications for Every Project
Big Timber BTX™ screws are ideal for a range of construction and remodeling needs, including wood framing, decks, porches, lateral bracing, fencing, siding, and roofing. Suitable for laminating beams, girders, posts, and general repair work, these screws meet the rigorous standards of both the International Building Code and International Residential Code.
