ANCHOR BOLTS
In the colossal world of construction and infrastructure, stability is everything. While steel columns and concrete foundations are the visible strength, the true integrity of a structure often rests on its smallest, yet most critical components: Anchor Bolts.
As a leading provider in the Indian fasteners industry, India Fasteners understands that an anchor bolt is not just a simple piece of metal; it is the vital link that secures structural elements, heavy machinery, and vital frameworks to concrete or masonry. From towering skyscrapers to crucial industrial installations, the performance of the entire system depends on the strength and reliability of these fasteners.
What are Anchor Bolts and Why are They Essential?
An anchor bolt is a specialized fastener used to attach objects or structures to concrete, brick, or stone. Its primary function is to transfer various types of load—namely tension forces (pull-out) and shear forces (lateral movement)—from the attached object to the base material.
In the challenging and diverse construction environment of India, where projects range from seismic-zone infrastructure to high-vibration industrial sites, the right anchor solution is paramount.
Key Benefits of High-Quality Anchor Bolts:
- Structural Stability: They ensure the immovable connection between a structure (like a steel column) and its foundation.
- Durability: Manufactured from materials like Carbon Steel, Stainless Steel, and specialty alloys, they offer high tensile strength and corrosion resistance.
- Load Bearing: They are engineered to safely support the full range of dynamic, static, and seismic loads.
- Versatility: A wide range of types allows for precise selection based on the base material and load requirement.
Essential Types of Anchor Bolts for Construction
Choosing the correct anchor bolt is a decision based on the application, the base material, and the required load capacity. Here are the most commonly used types of anchor bolts in India:
| TYPE | MECHANISM | USED FOR | FEATURES |
| Wedge Anchor Bolt | Mechanical expansion via an expanding clip/wedge. | Heavy-duty structural applications, securing structural steel, and industrial machinery to solid concrete. | Extremely high pull-out strength in solid concrete. |
| Sleeve Anchor Bolt | A bolt tightened inside a cylindrical sleeve causes the sleeve to expand. | Medium-duty applications in concrete, brick, or block (solid or hollow), such as handrails and light equipment. | Versatile for various base materials and easier to remove. |
| Chemical Anchor Bolt | A threaded rod is set into a pre-drilled hole using a chemical resin (epoxy/polyester). | Specialized, high-load, and seismic applications, where maximum pull-out resistance is crucial. | Provides a stress-free, watertight, and extremely high-strength bond. |
| L-Type Anchor Bolt | A bent, typically non-expanding, bolt with a 90° bend at one end, cast into wet concrete. | Pre-installing anchors in new concrete foundations for columns, equipment bases, and light poles. | Provides maximum embedment depth and reliable pull-out resistance via the bent end. |
| Drop-In Anchor | A female-threaded anchor that is internally expanded using a setting tool. | Flush-mount, overhead applications in solid concrete, ideal for suspended ceilings, sprinkler systems, and threaded rod suspension. | Leaves a flush surface and is ideal for accepting various bolts or rods. |
