Large Diameter Concrete Screws for Heavy-Duty Anchoring
When the job calls for maximum strength, large diameter concrete screws are the answer. Designed to handle heavier loads and critical connections, these heavy-duty masonry fasteners are built for structural anchoring into concrete, brick, or block. With deeper threads and increased surface contact, they deliver higher shear and pullout values, perfect for industrial, commercial, or code-driven construction applications.
When to Use Large Diameter Masonry Screws
These screws are engineered for high-load applications where smaller anchors or standard screws won’t cut it:
- Mounting structural brackets, ledger boards, or framing anchors
- Securing heavy machinery or racking systems
- Supporting beams, guardrails, or safety equipment
- Applications requiring code compliance (ICC, IAPMO, etc.)
They also reduce the need for traditional wedge or sleeve anchors, saving time while still meeting structural standards.
Trusted Brands of Large Diameter Screws at Fasteners Plus
Tapcon LDT (Large Diameter Tapcon)
Tapcon’s LDT line is a code-recognized solution for anchoring structural loads into concrete. Featuring a high-low thread design and durable Climaseal® corrosion-resistant coating, these anchors drive easily and hold tight. Choose from hex washer or flat head styles, available in multiple diameters and lengths for job-specific flexibility.
Simpson Strong-Tie Titen HD & Turbo
The Simpson Titen HD® and Titen Turbo™ series offer premium performance with high-strength steel and innovative thread geometry. Titen HD anchors are code-approved for cracked and uncracked concrete, seismic zones, and anchoring into grout-filled block. Titen Turbo reduces torque during installation, extending tool life and minimizing installer fatigue. Both series are ideal for structural retrofits, ledgers, and heavy equipment anchoring.
Conquest Large Diameter Concrete Screws
Conquest offers high-quality, large diameter concrete screws at competitive pricing, trusted by builders who need bulk performance at scale. These anchors feature aggressive thread design and hardened steel construction for reliable installation in solid concrete or block. Excellent for general construction, racking, and heavy-duty framing projects.
Material Types of Large Diameter Concrete Screws
Choosing the right material finish is just as important as selecting the right size. Large diameter concrete screws are available in several finishes to match your job site environment:
- Zinc-Plated: Ideal for interior or dry environments. Zinc plating offers basic corrosion resistance at a budget-friendly price point, perfect for indoor structural framing, equipment anchoring, or low-moisture applications.
- Galvanized: Provides enhanced corrosion resistance for general exterior use. This is a great option for garages, outdoor framing, or industrial spaces with occasional moisture exposure. Meets many code requirements for treated lumber contact.
- Stainless Steel: Built for the toughest environments: coastal, chemical, or high-moisture zones. Stainless steel screws offer superior corrosion resistance and are ideal for mission-critical or long-term installations where rust is not an option.
If your application involves exposure to moisture, treated wood, or corrosive chemicals, upgrading from zinc to galvanized or stainless can dramatically extend the lifespan of your fastener, and your structure.
How to Install Large Diameter Concrete Screws
- Drill the proper pilot hole: Use a hammer drill and a concrete drill bit size specified by the manufacturer. These screws require precision.
- Clear the debris: Blow out or brush the hole to improve holding power and prevent premature thread damage.
- Drive with consistent pressure: Use an impact or torque-controlled drill to seat the fastener snugly. Avoid over-torquing, especially near slab edges or in hollow block.
Always follow embedment depth recommendations to meet structural load values and ensure code compliance.
FAQs About Large Diameter Masonry Screws
Are these stronger than wedge anchors?
In many cases, yes. Large diameter concrete screws offer comparable or superior holding power with faster installation and no secondary expansion. However, always compare load tables and required specs for your application.
Do I need epoxy or adhesive with these?
No. These are mechanical anchors and require no chemical bonding. Their performance comes from thread engagement and proper embedment into solid base material.
What materials do they work in?
These fasteners are best in fully cured concrete, grout-filled block, or high-strength brick. Avoid use in lightweight block or uncured concrete unless manufacturer guidelines allow.
Can these be used in seismic zones?
Yes, several options (like Simpson Titen HD) are rated for seismic applications and cracked concrete. Check ICC-ES reports or ESR listings for specifics.
