Product Description

Introducing our revolutionary Concrete Self-Tapping Anchor Bolt—an advanced post anchoring fastener that ingeniously creates a secure anchoring effect in concrete through robust, hard threads. Explore the multi-dimensional analysis below:

1, Core Features

1. Self-Attack Anchoring Mechanism

Harnessing the power of high-strength threads (typically crafted from grade 10.9 or above carbon steel), this bolt directly penetrates the concrete hole wall, forming a solidly interlocked threaded connection with no requisite for pre-drilling or chemical bonding agents. Its immense anchoring strength is validated through rigorous destructive tensile testing, where the concrete cone's failure often precedes that of the anchor bolt itself.

2. Reversible Installation Design

Enjoy the flexibility of disassembly with an adjustable rotation direction, making it ideal for temporary fixations such as scaffolding or formwork support. This feature significantly cuts down on engineering renovation expenses.

2, Technical Parameters and Adaptability

1. Principle of Specification Matching

The anchor bolt diameter must strictly match the corresponding opening diameter (e.g., M8 anchor bolt for 8mm hole). Various length models (e.g., 6 × 35, 6 × 55) are available to suit different substrate thicknesses, ensuring that the anchoring depth meets your structural bearing needs.

2. Material Performance Grading

• Basic Version: Crafted from Grade 8.8 or higher carbon steel, this version is designed for conventional environment applications.

Anti-Corrosion Enhanced Version: Boasting 410 stainless steel treated with anti-corrosion measures, this version withstands harsh conditions like marine climates and chemical exposure.

High Strength Version: Using 12.9 grade carbon steel, this version is perfect for securing heavy equipment and fortifying against seismic activity.

3, Application Scenarios

1. Building Structure Reinforcement

Achieve rapid anchoring when installing seismic supports and suspension systems in concrete beams, slabs, and columns, ensuring the substrate's integrity remains uncompromised.

2. Equipment Installation

Ideal for securing curtain wall keels and mechanical/electrical pipeline supports, these bolts accommodate complex spatial layouts with their small margin installation feature.

3. Temporary Works

In dynamic settings like event venues and exhibition spaces, experience swift detachment of scaffolding and stage structures with ease.

4, Technical Advantages

1. Construction Efficiency

The installation duration per bolt is slashed by over 60% compared to traditional expansion anchor bolts, eliminating waiting time for adhesive curing.

2. Bearing Capacity

In C30 concrete, these anchor bolts boast impressive tensile bearing capacities of 8-15kN and shear capacities of 5-10kN, depending on specific specifications.

3. Environmental Adaptability

With material upgrades, our anchor bolts thrive in temperatures ranging from -20 ºC to 80 ºC, offering IP68 dust and water resistance for unparalleled durability.

5, Selection and Construction Points

1. Substrate Evaluation

Ensure concrete strength of C25 or higher, crack width ≤ 0.3mm, and appropriate steel density to prevent conflicts between anchor bolts and rebar.

2. Tool Matching

Opt for an electric wrench with torque control, maintaining installation torque within ± 15% of the nominal value to ensure precision.

3. Quality Control
