Our Wedge Anchors represent the industry standard for high-strength, permanent fastening in solid concrete. Designed for critical structural and seismic applications, these anchors provide unparalleled shear and tensile strength by creating a powerful mechanical lock within the base material. Engineered for reliability and performance, they are the preferred choice for construction professionals, engineers, and contractors who demand absolute confidence in their fastening systems.
Key Features & Benefits
Maximum Load Capacity: Achieves exceptional holding values through a unique wedge-and-sleeve mechanism that expands forcefully against concrete upon tightening, creating a permanent, vibration-resistant connection.
Bolt-Projection Design: Features a recognizable threaded bolt projecting above the surface, allowing for easy attachment of structural elements, machinery, pipe hangers, and safety systems without specialized tools.
Permanent Installation: Once installed and torqued, the anchor cannot be removed without destroying the concrete, making it ideal for safety-critical and permanent installations.
Corrosion-Resistant Options: Available in high-quality materials including Hot-Dipped Galvanized steel, Stainless Steel (304 & 316), and Zinc Plated finishes to withstand harsh industrial, marine, and exterior environments.
Code-Compliant & Certified: Manufactured to meet or exceed relevant international standards (such as ASTM, ICC-ES). Ideal for applications requiring compliance with building codes and engineering specifications.

Installation Guide (Simplified)
1. Drill: Drill a hole in the concrete using a hammer drill and a carbide-tipped bit of the specified diameter. Hole depth must exceed anchor length to accommodate debris.
2.Clean: Thoroughly clean the hole of all dust and debris using a brush, vacuum, or compressed air.
3.Insert: Place the anchor through the fixture into the clean hole. Ensure the minimum embedment depth is met.
4.Tighten: Hand-tighten the nut against the washer and fixture, then use a torque wrench to apply the final specified torque. This action draws the wedge up, expanding the sleeve for a secure lock.
