Made in China Concrete Fasteners Anchor Bolts M12 Stainless Steel Wedge Anchor

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Concrete Fastening: Designed to anchor heavy loads into concrete structures using a wedge expansion mechanism, ensuring secure fixation in masonry and concrete.
  • M12 Thread Compatibility: Features an M12 metric thread standard (ISO-compliant) for precise and reliable connections in construction and industrial applications.

Key features

  • 1. Stainless Steel Corrosion Resistance

    • With a stainless steel body, you can ensure long-lasting durability in harsh environments like marine settings or industrial zones, outperforming carbon steel anchors prone to rust.

  • 2. Hexagonal Head for Tool-Friendly Installation

    • With a precision-engineered hexagonal head, you can easily tighten or loosen the bolt using standard wrenches or sockets, simplifying installation compared to non-hex designs.

  • 3. Wedge Anchor Mechanism for Secure Concrete Fixing

    • With a patented wedge sleeve design, you can achieve a high-tension grip in concrete walls, providing 2x stronger load-bearing capacity than plastic anchors.

  • 4. ISO Compliance for Global Reliability

    • With ISO certification, you can meet international safety and quality standards, ensuring performance consistency compared to non-certified alternatives.

  • 5. Metric-Standard Customization for Versatile Use

    • With M12 threading and metric measurements, you can adapt to diverse project requirements, offering greater compatibility than imperial-standard anchors.

Product details

Made in China Concrete Fasteners Anchor Bolts M12 Stainless Steel Wedge Anchor

Our M12 Stainless Steel Wedge Anchor is engineered for robust fastening in demanding environments. Crafted from ISO-certified stainless steel, these anchors deliver exceptional corrosion resistance and load-bearing capacity. The hexagonal head and precision-machined threads ensure secure installation, while the wedge design guarantees reliable expansion in concrete and masonry.

Supplier's note

  1. Technical Breakthroughs:

    • Wedge Design: Pull-out resistance improved by 25% vs. traditional anchors.
    • Passivation Treatment: Doubles corrosion resistance in marine environments.
    • Hexagonal Head: 30% faster installation with standard wrenches.

  2. Version Selection Guide:

    • Base Model: Ideal for residential or light commercial use (e.g., mounting shelves or light fixtures).
    • Advanced Model: Suited for industrial applications requiring higher load capacity (e.g., securing machinery bases).
    • Pro Model: Designed for extreme environments (e.g., offshore platforms or chemical plants) with triple the industry-standard corrosion resistance.

Example Use Case:
With the Pro Model’s 780N/mm² thread strength, you can safely anchor heavy industrial equipment in corrosive coastal zones. Its ISO 15k corrosion rating ensures longevity even under prolonged saltwater exposure. Pair it with 100mm length for deep concrete installations, achieving 20% faster setup than competitors’ hex bolts.
