Concrete Wedge Anchors
Concrete Wedge Anchors
Heavy-Duty Anchoring for Structural Concrete Applications
Concrete wedge anchors are high-strength mechanical fasteners engineered to secure structural and non-structural components into solid concrete. Relying on a proven mechanical wedging action, these anchors expand against the concrete as they are tightened, creating exceptional holding power for critical load-bearing installations. Their reliability, ease of installation, and long-term performance make wedge anchors a trusted solution across construction, industrial, and infrastructure projects.
How Concrete Wedge Anchors Work
Mechanical Expansion for Superior Holding Strength
Wedge anchors are installed through the fixture and into a pre-drilled hole in concrete. As the nut is tightened, the anchor’s expansion clip wedges firmly against the concrete wall, delivering vibration-resistant, permanent anchoring. This design ensures consistent performance under tension, shear loads, and dynamic forces.
Material and Finish Options
Built for Durability and Corrosion Resistance
Concrete wedge anchors are available in multiple materials to match environmental conditions and performance requirements:
-
Carbon Steel – Cost-effective for interior, dry applications
-
304 & 316 Stainless Steel – Excellent corrosion resistance for outdoor, marine, and chemical-exposed environments
Available finishes include Clear Zinc Cr3 for indoor use, Hot-Dipped Galvanized for exterior exposure, and Mechanically Galvanized coatings ideal for uniform protection and grounding applications.
Sizes and Configurations
Versatile Options for Every Job
Wedge anchors are offered in diameters from 1/4" to 1-1/4" and lengths from 1-3/4" to 12", with UNC coarse threads for easy installation. Common head styles include hex head, flat head, and rod-hanging versions to accommodate a wide range of mounting needs.
Common Applications
Trusted for Load-Bearing Installations
Concrete wedge anchors are widely used to secure steel columns, base plates, machinery, racking systems, handrails, HVAC units, electrical panels, conduit supports, and guardrails. Stainless steel options are preferred in wastewater, coastal, and corrosive environments, while galvanized anchors excel in semi-exposed conditions.
Proven Performance You Can Rely On
