Galvanized Concrete Self-Tapping Anchor | Hex Flange Head Manufacturer
product detail
Description of Galvanized Concrete Screw Anchor
Galvanized Concrete Self-Tapping Anchors are self-tapping anchoring fasteners specifically designed for concrete, masonry, and block substrates. The product features a hexagonal flange head with an integrally molded flange and anti-slip serrated bottom, replacing the traditional combination of flat washers and spring washers. The screw section uses a special self-tapping thread design with a cutting edge at the tail, allowing direct screwing into pre-drilled holes.
The core value of galvanized concrete self-tapping anchors lies in: no expansion tubes, no chemical anchors, and no waiting for curing—simply drill and install, significantly saving construction time and labor costs. The product complies with international standards such as ETAG 001 and EAD 330747-00-0601 and has obtained ETA European technical assessment certification. It is widely used in building curtain walls, steel structure fixing, pipe support installation, and railing fixing.
As a professional supplier of galvanized self-tapping anchors and a manufacturer of hexagonal flange head galvanized anchors, we offer a full range of specifications and OEM/ODM non-standard customization services. Direct supply from the source factory, transparent pricing for galvanized anchor bolts, and full quality control throughout the process.
Advantages of Galvanized Concrete Screw Anchor
Self-tapping threads, no pre-embedding required, highly efficient installation
Galvanized concrete self-tapping anchors feature a self-tapping thread design with a cutting edge at the end, allowing direct screwing into pre-drilled holes. Installation requires no expansion tubes, no chemical anchors, and no waiting for curing—simply drill and install, significantly improving construction efficiency. Compared to traditional expansion anchors, installation time can be reduced by more than 50%.
Hexagonal flange head, integrated gasket, anti-loosening and leak-proof
The hexagonal flange head design is one of the core advantages of this product. The flange and head are integrally molded, with anti-slip serrations on the bottom, replacing separate flat washers and spring washers:
Increased contact area: The flange evenly distributes locking pressure, preventing damage to the substrate surface.
Anti-loosening and anti-reverse: The anti-slip serrations on the bottom of the flange effectively prevent vibration-induced loosening.
Simplified assembly: No additional accessories required, making installation faster.
Removable and reusable, economical and flexible
Galvanized self-tapping anchors can be completely removed after installation, leaving no metal residue. The anchors are reusable, making them more economical in temporary fixing, equipment debugging, and other scenarios.
Factory direct supply, high cost performance
As a source manufacturer of galvanized concrete anchors and a supplier of galvanized self-tapping anchors, we have complete production lines for cold heading, thread rolling, heat treatment, and surface treatment. Our direct supply model makes our galvanized anchors more competitively priced, eliminating middlemen and ensuring full quality control.

Production Process
Application of Galvanized Concrete Screw Anchor
Building curtain wall and steel structure fixation
Galvanized concrete self-tapping anchors are ideal anchors for building curtain walls and steel structures. It is used to connect curtain wall keels, steel beam supports, steel structure column feet and concrete base materials. The hexagonal flange head provides reliable fastening and anti-loosening performance, and the galvanized layer ensures that it will not rust after long-term outdoor exposure.
Pipe supports and equipment installation
Used for concrete foundation anchoring of pipe supports, cable trays, HVAC equipment, and fire protection systems. The self-tapping thread design makes installation convenient and efficient, greatly shortening the construction period. Hot-dip galvanized galvanized concrete self-tapping anchors are particularly suitable for use in humid and corrosive environments.
Guardrails and safety facilities fixed
Used for concrete base fixing of road guardrails, bridge railings, stair handrails, and safety fences. High-strength anchoring capacity ensures the reliability of safety facilities under impact loads.
Renewable energy and outdoor facilities
Suitable for concrete anchoring of solar photovoltaic brackets, wind power generation foundations, and communication base stations. Corrosion resistance and weather resistance make it perform well in long-term outdoor exposure environments.
Industrial Equipment and Heavy Machinery Fundamentals
Used for concrete foundation anchoring of compressors, generators, pump units, and conveying equipment. High strength level (level 8.8 concrete screw anchor/level 10.9 concrete screw anchor) and reliable anchoring capacity meet the strict requirements for foundation fixation of industrial equipment.

FAQs
Q1: What are the installation steps for galvanized concrete self-tapping anchors? What precautions should be taken?
A: Installation steps: ① Drilling – Use a rotary hammer drill to drill a hole in the concrete substrate matching the anchor diameter; ② Hole cleaning – Use a manual air blower to remove dust from the hole at least 4 times; ③ Screwing – Use a socket wrench or impact wrench to screw the anchor in, applying downward pressure to initiate the self-tapping action. Precautions: The drilling depth should be slightly greater than the anchor length to accommodate cutting dust; please refer to the technical parameter table for installation torque; for detailed installation instructions, please request the installation technical manual.
Q2: How to choose between electro-galvanized, hot-dip galvanized, and mechanically galvanized concrete screw anchors?
A: Electro-galvanized (blue-white zinc/color zinc) concrete screw anchors are economical, offer good rust prevention, and are suitable for general indoor environments and dry conditions. Hot-dip galvanized concrete screw anchors have a thick coating and strong corrosion resistance, suitable for outdoor exposure, high humidity environments, and coastal areas. Mechanically galvanized concrete screw anchors offer a uniform coating and eliminate the risk of hydrogen embrittlement, making them suitable for high-strength bolts and outdoor applications. Dacromet concrete screw anchors offer superior corrosion resistance (up to 1000 hours of salt spray), making them suitable for marine environments and high-salt-spray areas. Selection recommendations: Electro-galvanized concrete screw anchors are generally recommended for construction projects; hot-dip galvanized or mechanically galvanized concrete screw anchors are recommended for outdoor, coastal, and corrosive environments. Please consult our galvanized concrete anchor manufacturer for professional selection advice.
Q3: What is the difference between galvanized concrete self-tapping anchors and traditional expansion anchors?
A: The main difference lies in their working principle and installation method. Expansion anchors rely on expansion force to generate frictional resistance for fixation, resulting in significant expansion stress on the substrate during installation, which can easily lead to cracking near edges. Galvanized concrete self-tapping anchors achieve anchoring through mechanical locking between the threads and concrete, without generating expansion stress, making them suitable for installations near edges and in close-pitch applications. Furthermore, galvanized self-tapping anchors are completely removable and reusable, while traditional expansion anchors are typically not. In cracked concrete, the mechanical locking of the threads of self-tapping anchors is superior to that of friction-dependent expansion anchors.
