Description

The Simpson Strong-Tie Bugle-Head Wood Screw Square Drive is built for decking projects that demand strength, corrosion resistance, and a clean finish. Made from 305 stainless steel, these screws provide long-lasting protection in outdoor environments.

Designed for smooth installation, the bugle head ensures flush countersinking for a professional appearance, while the square-drive recess reduces cam-out for secure driving. A sharp Type 17 point delivers fast starts, and coarse threads draw decking tightly to the substrate for a solid hold in cedar, redwood, and preservative-treated woods.

Key Features

  • 305 stainless steel options - deliver dependable corrosion resistance outdoors
  • Bugle head design - provides flush countersinking for a clean, professional finish
  • Square-drive recess - reduces cam-out and ensures secure driver engagement
  • Type 17 point with coarse threads - fast starts and strong holding power in decking materials
