Premium M6-M24 Wedge Anchors: Reliable Heavy-Duty Concrete Fastening
Our M6-M24 Wedge Anchors, also known as Through Bolts, are the professional standard for securing structural elements to solid concrete. Engineered for “bottom-up” expansion, these concrete expansion bolts feature a specialized stainless steel clip that expands against the hole wall as the nut is torqued. This creates a mechanical interlock with superior pull-out resistance. Whether you are installing warehouse racking or heavy industrial machinery, our wedge anchors offer the reliability required for life-safety applications.
As a leading wedge anchor factory, we utilize automated cold-heading and precision threading to ensure every bolt meets rigorous load-bearing standards. Available in SS316 for coastal environments and Grade 8.8 Carbon Steel for structural projects.
- Fully Threaded Design: Allows for adjustable embedment depths, making them versatile for various fixture thicknesses.
- High-Performance Clip: Our 360° expansion clip ensures uniform contact with the concrete, reducing the risk of anchor slip even under dynamic loads.
- Corrosion Protection: Choose from Hot Dip Galvanized (HDG) for outdoor infrastructure or Zinc Plating for cost-effective indoor installations.
- Simple Installation: No need for specialized tools—just drill a hole the same diameter as the anchor, drive it in, and tighten.
Select the correct metric wedge anchor based on the drill bit diameter and minimum embedment depth required for your concrete strength.
| Thread Size | Drill Bit Dia. | Min. Embedment | Max. Fixture Thickness |
|---|---|---|---|
| M8 | 8 mm | 40 mm | 15 – 50 mm |
| M10 | 10 mm | 50 mm | 20 – 70 mm |
| M12 | 12 mm | 65 mm | 25 – 100 mm |
| M16 | 16 mm | 80 mm | 30 – 120 mm |
| M20 | 20 mm | 105 mm | 40 – 150 mm |
Our M8-M24 Concrete Fasteners are essential for high-visibility sectors:
- Structural Steel: Securing base plates for columns, beams, and mezzanine levels.
- Warehouse Racking: Anchoring heavy-duty pallet racks to ensure seismic and operational safety.
- Mechanical Equipment: Mounting HVAC units, conveyors, and CNC machines to factory floors.
- Safety Infrastructure: Installing guardrails, handrails, and stadium seating.
Q: Can wedge anchors be used in brick or block?
A: We recommend using them only in solid concrete. For hollow block or brick, sleeve anchors or chemical anchors are more suitable as wedge anchors exert high expansion pressure.
Q: What is the difference between SS304 and SS316 wedge anchors?
A: SS304 is excellent for general outdoor use. SS316 contains molybdenum, providing superior resistance to chlorides and salt spray, making it essential for marine or chemical plant environments.
