Wedge Expansion Anchors

Wedge anchors are mechanical expansion fasteners engineered for securing fixtures into solid concrete. Once inserted and torqued, the anchor expands at the base, locking into place for a dependable, long-term hold. They are commonly used in structural connections, heavy equipment installations, and industrial construction.

Engineered for Anchoring Into Solid Concrete


  • Designed for Structural and Load-Bearing Applications

    • Wedge anchors are used to secure heavy materials like steel columns, machinery, base plates, or racking systems directly into concrete surfaces.


  • Expansion Locking Mechanism Ensures Long-Term Stability

    • The anchor expands near its embedded end when torqued, delivering a tight grip that resists pullout and vibration over time.


  • Hex Head or Threaded Bolt Tops for Versatile Compatibility

    • Options include hex bolts and threaded variants for use with nuts or washers, adapting to different installation and assembly requirements.


  • Built for Static and Dynamic Load Conditions

    • They are suitable for environments with static loads or vibration, such as warehouses, mechanical rooms, and structural framing.


  • Suitable for Indoor and Outdoor Use With Corrosion-Resistant Options

    • Wedge anchors are available in materials like stainless steel or zinc-plated steel to meet corrosion resistance standards in harsh or exposed conditions.
