Description

.275" x 8" Conquest Structural Screw - T-30 Star Drive, Pkg 50

The .275" x 8" Conquest Structural Screw is built for structural wood assemblies that require substantial penetration and uncompromising holding strength. With its extended 8" length, this screw is ideal for fastening large dimensional lumber, laminated beams, and multi-layer framing members. The T-30 star drive provides excellent torque control, helping installers maintain steady, accurate drives even in dense material.

Note: ICC-ES code approved for structural wood applications.

.275" x 8" Long-Length Structural Wood Screw with T-30 Drive

Engineered for deep embedment, this heavy-duty structural screw combines a thick .275" diameter with aggressive self-tapping threads to secure demanding wood-to-wood connections. It is well suited for projects where extended reach and strong clamping force are critical to overall structural performance.

Key Features

  • 8" Extended Length: Designed for thick, multi-member structural assemblies.
  • .275" Heavy Structural Diameter: Supports high-load wood connections.
  • T-30 Star Drive: Delivers reliable torque transfer and reduced cam-out.
  • Self-Tapping Thread Design: Cuts cleanly into dense lumber without predrilling in most cases.

Common Applications

  • Large Beam Connections: Secures laminated and built-up beams.
  • Post and Timber Assemblies: Fastens heavy structural components.
  • Deck Substructure Reinforcement: Strengthens load-bearing members.
  • Outdoor Structural Builds: Ideal for pergolas and heavy wood framing.
  • Framing Upgrades: Adds strength to existing wood construction.

Installation Tips

  • Pre-Align Components: Clamp thick members before driving.
  • Drive at Controlled Speed: Allow threads to engage progressively.
  • Seat Head Flush: Stop once the head is firmly seated against the surface.

Screws are flawless

I was shocked with the cost of shipping, but the 50 screws I ordered were exactly what I needed for my deck rebuild. Shipping was almost as much as the screws themselves. I could understand that for a larger order, but for 50 screws, I felt that was unnecessary. A few dollars would cover the real shipping cost for the small box of screws.
