Conquest Large Diameter Concrete Screws – Galvanized are engineered for serious holding power in concrete, block, and brick. Whether you’re anchoring sill plates, machinery, racking systems, or structural framing, these heavy-duty fasteners are built to handle high-load applications with confidence. Designed with a robust thread profile, they cut into concrete with minimal torque while delivering high pullout resistance.
Made from hardened steel with a galvanized coating, they provide strong corrosion protection for both interior and exterior jobs. These screws are the go-to choice for contractors and pros who need a fastener that installs cleanly and holds tight, without the hassle of anchors or inserts.
With multiple diameters and lengths available, it’s easy to match the screw to your exact project needs. Each size comes with a hex washer head for superior drivability and increased bearing surface.
Key Features:
- Galvanized Coating: Corrosion-resistant finish extends product life in demanding environments.
- Hex Washer Head: Offers strong grip and even torque during installation.
- High Thread Engagement: Aggressive threads deliver secure fastening in concrete and masonry without anchors.
- Large Diameter Strength: Ideal for heavy-duty loads in structural applications.
- Multiple Sizes Available: Choose from a range of diameters and lengths to match your project specs.
Applications:
- Wood-to-concrete framing
- Machinery and equipment anchoring
- Electrical and plumbing fixtures
- Sill plates and ledger boards
- Storage racking, shelving, and pipe supports
Installation Tips:
- Pre-drill a hole using a carbide-tipped masonry bit (follow manufacturer recommendations for bit size).
- Clear out dust and debris from the hole for optimal hold.
- Drive the screw using an impact driver or socket wrench until the head is flush.
- Do not over-torque; let the threads do the work.
