Durable M6-M24 Expansion Anchors for Secure Concrete Fastening
Our Expansion Anchors are engineered to provide maximum holding power in solid base materials. These mechanical fasteners work by expanding against the walls of a pre-drilled hole when the nut is tightened. We offer a comprehensive range of concrete expansion bolts, including the industry-standard Wedge Anchors and versatile Sleeve Anchors, ensuring the safety and stability of your construction projects.
Manufactured from high-tensile carbon steel and corrosion-resistant A4 Stainless Steel, these anchors are suitable for both indoor dry environments and harsh outdoor or marine conditions.
- Wedge Anchors (Through Bolts): The most popular choice for heavy-duty structural applications. Their simple design allows for easy installation through the fixture.
- Sleeve Anchors: Ideal for versatile fastening in concrete, brick, or block. The outer sleeve expands along its entire length for a firm grip.
- Drop-in Anchors: Female threaded anchors used with bolts or threaded rods, perfect for hanging pipes, HVAC ducts, and fire sprinkler systems.
- Shield Anchors: Heavy-duty four-way expansion anchors designed for older or lower-quality masonry.
| Thread Diameter (D) | Drill Bit Size | Min. Embedment | Typical Load (kN) |
|---|---|---|---|
| M6 | 6 mm | 35 mm | 2.5 – 4.0 |
| M8 | 8 mm | 45 mm | 4.5 – 6.5 |
| M10 | 10 mm | 55 mm | 7.0 – 9.5 |
| M12 | 12 mm | 70 mm | 11.0 – 15.0 |
| M16 | 16 mm | 90 mm | 18.0 – 25.0 |
| M20-M24 | 20/24 mm | 120+ mm | Heavy Load |
- Structural Steel: Anchoring columns, beams, and base plates to concrete foundations.
- Public Infrastructure: Installation of bridge railings, sound barriers, and stadium seating.
- Mechanical Equipment: Securing heavy industrial machinery and conveyor systems to prevent vibration movement.
- Warehouse Racking: Fixing pallet racks and storage shelving to ensure warehouse safety.
- Drill a hole using a hammer drill and a bit that matches the anchor diameter.
- Clean the hole thoroughly using a brush and air pump to remove dust (crucial for load capacity).
- Insert the expansion anchor through the fixture into the hole.
- Tighten the nut to the recommended torque value using a torque wrench. The expansion clip or sleeve will expand, locking the bolt in place.
