Description

Conquest Structural Screws with T-30 star drive are engineered for serious holding power in structural wood applications. Whether you're working on deck framing, ledger boards, or general wood construction, these screws deliver superior strength, consistent drive, and peace of mind.

Each screw features a T-30 star drive for maximum bit engagement and minimal slipping, allowing for quick and precise installs. The aggressive self-tapping thread eliminates the need for pre-drilling, even in dense wood, saving time on the jobsite.

With a yellow zinc coating, these structural screws offer excellent corrosion resistance for both interior and exterior projects. ICC code approval makes them a trusted choice for contractors needing dependable fastening that meets building requirements.

Key Features:

  • ICC-ES Code Approved: Certified for structural applications
  • T-30 Star Drive: Reduces cam-out and bit stripping
  • Self-Tapping Threads: No pre-drilling needed, even in dense wood
  • Yellow Zinc Finish: Corrosion-resistant for indoor and outdoor use

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.

very competent screws

These torx flathead screws appear to be of high quality. I have sunk about 200 so far and
not had a single break or torx strip. Some screws were driven so hard that the geared driver drill required a right-angle brace to keep control of it.
