Get the job done efficiently with Flat Head, Square Drive Construction Screws from Fasteners & Fittings. These screws are engineered for strength and performance in all your interior construction projects. Featuring a reinforced neck, they provide increased driving torque, while the bugle head allows for self-countersinking, creating a clean, flush finish.

The square drive design ensures a no-slip, tight fit during installation, reducing the risk of stripping. With coarse threads and sawtooth technology, these screws offer extra holding power, faster draw-down, and smoother driving without splitting the wood. The extra sharp point easily penetrates wood, eliminating the need for pre-drilling.

  • Yellow Zinc Dichromate Plated: Adds protection against corrosion for interior use
  • Reinforced Neck: Increases driving torque for tougher tasks
  • Bugle Head: Self-countersinking for a smooth, clean finish
  • Square Drive: Provides a no-slip, cling fit for easy driving
  • Coarse Threads & Sawtooth: Ensures extra holding power and faster installation without splitting
  • Extra Sharp Point: Easily penetrates wood without pre-drilling
