Mechanical Anchor Bolt Manufacturers

Mechanical Anchor Bolts for Demanding Concrete Connections

As a Mechanical Anchor Bolt Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.

We are a China-based manufacturer and supplier of mechanical anchor bolts, producing high-strength fastening solutions for concrete, masonry, and structural steel applications. Our range covers expansion anchors, wedge anchors, and undercut anchors, all engineered to deliver reliable pull-out and shear resistance in new construction, retrofit, and infrastructure projects.

With a 32,000 m² production plant and an annual capacity of 8,000 tons of construction hardware, we combine automated cutting, stamping, CNC machining, and laser processing to produce anchors that meet international quality standards. Our engineering team supports OEM/ODM customization, from material selection to packaging, ensuring each anchor is configured for the specific base material, load requirement, and installation method of your project.

Our Mechanical Anchor Bolt Range

We supply several mechanical anchor types, each with a distinct anchoring principle. The table below summarizes the main configurations we produce and their typical applications.

We also produce related fasteners such as anchor bolts and other concrete embedded parts, allowing you to source a complete anchoring package from one factory.

Materials and Finishes

Anchor performance depends on material grade and surface protection. We manufacture from stainless steel (e.g., 304, 316), carbon steel, and low-alloy steel, with finishes selected for the service environment.

• Stainless steel: for corrosive or coastal environments, offering long-term durability.
• Carbon steel with zinc plating: for indoor or dry applications, cost-effective and reliable.
• Hot-dip galvanized: for outdoor or humid conditions, providing thick corrosion protection.

For each order, we confirm the required material grade, finish thickness, and any specific standards (e.g., ASTM, EN) to ensure the anchor meets your project specification.

Critical Specifications and Performance

Mechanical anchors must be selected based on the base material (concrete grade, cracked or uncracked), edge distances, spacing, and load type (static, dynamic, seismic). We provide technical data for each anchor, including:

• Diameter range: typically M6 to M24, with custom sizes available.
• Embedment depth and minimum base thickness.
• Characteristic tensile and shear resistance values.
• Recommended installation torque and drill bit size.

Our engineering team can assist in anchor selection based on your load calculations and base material conditions. We also offer anchors with special features, such as anti-rotation lugs or reduced edge-distance designs, for challenging installations.

Configuration and Customization

As a flexible manufacturer, we support both standard and fully customized anchors. You can specify:

• Thread length, overall length, and head style (hex, flat, etc.)
• Expansion sleeve design (e.g., double expansion for cracked concrete)
• Material grade and finish
• Marking and packaging requirements

We produce from customer drawings or samples, using in-house tooling and CNC machining to achieve tight tolerances. Our R&D team can also develop new anchor designs for specific project needs.

Quality Assurance and Testing

Quality is embedded in our production process. We conduct in-process inspections and final checks on 99.99% of finished products, using our own laboratory equipment including spectrometers, tensile testers, and surface testers. This allows us to verify chemical composition, mechanical properties, and dimensional accuracy.

We hold ISO9001 and have factory audits from BV, SGS, and TUV, confirming our commitment to international quality standards. For each batch, we can provide material certificates and test reports upon request.

Installation and Maintenance

Mechanical anchors are designed for quick installation without special curing time. We provide clear installation instructions, including hole drilling, cleaning, and torque values. For critical applications, we can supply installation training or on-site support (subject to project scope).

Maintenance is minimal, but periodic inspection is recommended in corrosive environments. We can advise on suitable materials and finishes to maximize service life.

Information We Use to Configure Your Solution

To prepare an accurate quotation and technical proposal, we need the following project information:

• Base material type and condition (concrete grade, cracked/uncracked, masonry)
• Required load capacity (tensile, shear, moment) and safety factors
• Anchor diameter, length, and quantity
• Environmental conditions (indoor/outdoor, humidity, chemical exposure)
• Applicable standards or approval requirements
• Delivery destination and packaging preferences

With this data, we can recommend the most suitable anchor type, material, and finish, and provide a detailed quotation with technical documentation.

FAQs

What is the difference between mechanical and chemical anchors?

Mechanical anchors rely on friction or mechanical interlock with the base material, providing immediate load capacity after installation. Chemical anchors use adhesive to bond the anchor to the concrete, which requires curing time. Mechanical anchors are often preferred for removable connections or when quick installation is needed.

Can you provide anchors for cracked concrete?

Yes, we offer expansion anchors and undercut anchors specifically designed for cracked concrete applications. These anchors have been tested to maintain performance in cracked conditions, and we can provide documentation upon request.

What is the minimum order quantity?

Our MOQ is flexible depending on the anchor type and customization level. For standard sizes, we can accommodate small trial orders. For large projects, we can scale up to meet your volume requirements.

Do you provide installation tools?

We can supply setting tools and drill bits as accessories. For undercut anchors, we offer the necessary undercutting tool to ensure proper hole preparation.

How do you ensure quality for large orders?

We implement strict quality control from raw material inspection to final packaging. Each production batch is tested, and we provide inspection reports. We also welcome third-party inspections before shipment.
