Shield anchor bolts consist of a threaded bolt, a metal sleeve (shield), and a cone-shaped expansion nut. The shield is typically made of steel and has grooves or ridges along its length. The expansion nut is placed over the threaded end of the bolt and is tapered to fit into the shield.
Installation: To install a shield anchor bolt, a hole is drilled into the concrete or masonry using an appropriate-sized drill bit. The shield anchor is then inserted into the hole. When the expansion nut is tightened, it pulls the bolt upward, causing the shield to expand and grip the surrounding material, providing a secure hold.
Load Capacity: Shield anchor bolts are capable of supporting significant loads, making them suitable for applications where strong and reliable connections are required. The load capacity depends on factors such as the size and type of anchor, the quality of the base material, and the proper installation technique.
Versatility: Shield anchor bolts are commonly used in a wide range of applications, including construction, carpentry, metal fabrication, and more. They can be used to anchor structural elements, such as steel beams or columns, as well as fixtures like handrails, machinery, shelving, and signage.
Materials: Shield anchor bolts are typically made of steel, which provides strength and durability. They are often zinc-plated or coated with other corrosion-resistant materials to enhance their longevity and protect against rust and corrosion.
Sizes and Variations: Shield anchor bolts are available in various sizes and lengths to accommodate different applications and load requirements. They may also come in different designs, such as single-expansion or double-expansion anchors, to suit specific installation needs.

READ MOREAs a Three Sheild Anchor Manufacturers, we match product configuration to the application, operating limits, interfaces and acceptance criteria defined for each project.
We are a professional Three Sheild Anchor manufacturer and supplier based in China, with a 32,000 m² production plant and an annual capacity of 8,000 tons of construction hardware. Our three shield anchors are engineered for reliable fastening into concrete, brick, and block, serving structural steel connections, heavy machinery anchoring, and facade support systems across global construction projects.
We produce both standard and custom three shield anchors, with a focus on material integrity, precise thread geometry, and consistent expansion performance. Our factory integrates automated cutting, stamping, CNC machining, and surface treatment lines, ensuring every batch meets the mechanical requirements of your application.
Our three shield anchors are available in two primary configurations, each tailored to different service environments and load demands:
| Model | Material | Finish | Typical Use |
|---|---|---|---|
| AZB01 | Stainless steel (e.g., SS304/316) | Plain or passivated | Corrosive environments, outdoor facades, coastal structures |
| AZB02 | Carbon steel | Zinc plated or hot-dip galvanized | Interior concrete, heavy machinery, general construction |
We also offer custom lengths, diameters, and thread forms to match project-specific embedment depths and pull-out requirements. Whether you need anchors for curtain wall brackets, steel column base plates, or seismic bracing, our range covers the mechanical performance you specify.
Each anchor consists of a threaded bolt, a slotted metal shield, and a cone-shaped expansion nut. During installation, tightening the nut draws the bolt upward, forcing the cone into the shield and expanding its segments against the hole wall. This creates a mechanical interlock that resists pull-out and shear forces.
We manufacture the shield with precise slot geometry to ensure uniform expansion even in irregular masonry. The bolt threads are rolled for fatigue resistance, and the cone is machined to a consistent angle for predictable clamping force.
Load capacity depends on anchor size, base material strength, and installation quality. We design our anchors to achieve consistent expansion in normal-weight concrete (C20/25 and above) and solid masonry. Our in-house tensile testing verifies ultimate pull-out values, and we can provide test reports for your approval.
Standard sizes range from M6 to M20, with lengths from 50 mm to 200 mm. We also produce non-standard diameters and lengths for special projects. Thread pitch follows ISO metric standards unless otherwise specified.
We operate a laboratory equipped with a spectrometer, tensile tester, and surface inspection tools. Every production batch is checked for chemical composition, mechanical properties, and dimensional accuracy. We perform 99.99% inspection on finished anchors, including thread gauge checks and visual surface examination.
Our quality system is certified to ISO9001, and we can supply material certificates, test reports, and conformity declarations as required by your contract. For large orders, we welcome third-party inspections before shipment.
We understand that standard catalogs don't cover every project. Our R&D team works from your drawings or samples to produce anchors with custom dimensions, special materials, or unique packaging. We also offer private labeling and mixed-container loading with other construction hardware from our range.
Our factory capabilities include automated cutting, stamping, CNC machining, and laser processing, allowing us to maintain tight tolerances even for complex geometries. We can also supply matching washers, nuts, and installation tools.
Proper installation is critical to anchor performance. We provide clear technical data sheets that specify recommended drill bit sizes, hole depths, and tightening torques. For example, an M10 anchor typically requires a 12 mm drill bit and a minimum embedment of 50 mm in concrete.
We advise customers to verify base material condition before drilling and to avoid over-tightening, which can cause concrete spalling. For seismic or dynamic loads, consult our engineering team for spacing and edge distance recommendations.

With this information, we can recommend the most suitable model from our product range or develop a custom solution. Our sales engineers respond within 12 working hours with technical feedback and a commercial offer.
AZB01 is made from stainless steel for corrosion resistance, ideal for outdoor or humid environments. AZB02 is carbon steel with a protective coating, offering higher strength at lower cost for dry interior applications.
Yes, we regularly produce custom lengths and diameters based on your project drawings. We can adjust thread length, shield dimensions, and overall anchor size to meet your embedment and load requirements.
We provide material certificates and tensile test reports for each batch. For specific projects, we can also arrange third-party testing to verify compliance with standards like ASTM or EN.
For standard sizes, we accept small trial orders starting from 500 pieces. For custom products, MOQ depends on tooling and material availability; we will confirm during quotation.
Our shield slots are precisely cut to allow uniform deformation. We also control the cone angle and surface finish to reduce friction, ensuring reliable setting even in hollow or soft brick.
Our portfolio also includes Facade System Of Aluminum for applications with different operating ranges, interfaces or integration requirements.
We will wholeheartedly provide you with high quality products, reasonable price, on-time delivery and attentive service.
