Description

The Conquest Structural Screw with T-30 Star Drive is built to outperform traditional lag screws in strength, speed, and ease of installation. Whether you're framing walls, constructing decks, or building pergolas, these structural fasteners are engineered for demanding wood-to-wood connections in residential, commercial, and outdoor projects.

Manufactured for durability and precision, these screws feature a T-30 star drive that resists cam-out and offers superior torque control. The self-drilling tip and aggressive thread pattern reduce the need for pre-drilling, helping you save time on every job. Designed with a corrosion-resistant coating, they’re tough enough for interior or exterior use — even in treated lumber.

Offered in multiple lengths and diameters, these structural screws meet code requirements for structural applications and provide a strong, lasting connection in every setting.

Features:

  • T-30 Star Drive Head: Reduces stripping and cam-out for a secure drive every time.
  • Self-Drilling Tip: Eliminates the need to pre-drill, increasing productivity.
  • High Thread Engagement: Delivers superior holding power and reduces wood splitting.
  • Corrosion-Resistant Coating: Suitable for both interior and exterior environments, including use in pressure-treated lumber.
  • Available Sizes: A range of diameters and lengths to match your specific building needs.

Applications:

  • Deck ledger attachments
  • Pergola beams and rafters
  • Wall framing and load-bearing wood connections
  • Fence stringers and rails
  • General structural wood assemblies

Installation Tips:

  • Use a T-30 star bit for optimal fit and torque control.
  • Drive screws flush with the surface — avoid overdriving to protect the wood.
  • For best results in structural applications, follow local building codes and fastener spacing guidelines.
