WEDGE ANCHOR BOLT A wedge anchor bolt is a mechanical fastener used to secure objects to solid concrete. It works by expanding inside a drilled hole when the nut is tightened. This expansion creates friction and mechanical interlock with the concrete, providing high load-bearing capacity. Key principle: Tightening the nut pulls the threaded stud upward, forcing the wedge clip to expand against the concrete wall. Wedge anchors are permanent anchors—once installed, they are difficult to remove without cutting. 2. Standard Sizes Common Diameters M6 (1/4') M8 (5/16') M10 (3/8') M12 (1/2') M16 (5/8') M20 (3/4') Common Lengths : Typically range from 40 mm to 300 mm (or 1-1/2' to 12') Length selection depends on: Fixture thickness Minimum embedment depth Concrete strength Why Wedge Anchor Bolts Are Important ? Wedge anchors are critical in construction and industrial settings because they: 1) Provide high tensile and shear strength 2) Offer reliable performance in solid concrete 3) Are easy to install with basic tools 4) Allow immediate loading after installation 5) Are suitable for structural and safety-critical connections They are often preferred over chemical anchors when speed and simplicity are required. Materials Used Carbon Steel - Most common, High strength, Requires protective coating Stainless Steel - A2 (304): General corrosion resistance, A4 (316): Marine, chemical, or coastal environments Alloy Steel (Heavy Duty) - Used for high-load structural applications, Often heat-treated Surface Finishes & Coatings The finish protects the anchor from corrosion and environmental damage. Finish Application 1) Zinc Plated - Indoor, dry environments 2) Hot-Dip Galvanized (HDG) - Outdoor, moderate corrosion 3) Mechanical Galvanized - Uniform coating, structural use 4) Stainless Steel - Wet, corrosive, marine environments 5) Epoxy Coated - Chemical plants, industrial floors Installation Overview 1) Drill hole to correct diameter and depth 2) Clean hole (air + brush) 3) Insert anchor through fixture 4) Hammer anchor until washer touches surface 5) Tighten nut to specified torque Correct torque is critical—under- or over-tightening reduces performance.
